Facebook is an American social networking service owned by the American technology conglomerate Meta Platforms. It was founded in 2004 by Mark Zuckerberg, along with his Harvard College roommates and fellow students Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes. The name Facebook derives from the face book directories often given to American university students.
The service was initially targeted to Harvard students only before gradually expanding to other universities in North America. Since 2006, Facebook has permitted registration by individuals aged 13 and older, with the exception of South Korea, Spain, and Quebec, where the minimum age is 14.
As of December 2023, Facebook reported approximately 3.07 billion monthly active users worldwide. As of July 2025, it was ranked as the third-most-visited website in the world, with 23 percent of its traffic originating from the United States. It was the most downloaded mobile application of the 2010s.
Facebook can be accessed from devices with Internet connectivity, such as personal computers, tablets and smartphones. After registering, users can create a profile revealing personal information about themselves. They can post text, photos and multimedia which are shared either publicly or exclusively with other users who have agreed to be their friend, depending on privacy settings. Users can also communicate directly with each other with Messenger, edit messages (within 15 minutes after sending), join common-interest groups, and receive notifications on the activities of their Facebook friends and the pages they follow.
Facebook has often been criticized over issues such as user privacy (as with the Facebook–Cambridge Analytica data scandal), political manipulation (as with the 2016 U.S. elections) and mass surveillance. The company has also been subject to criticism over its psychological effects such as addiction and low self-esteem, and over content such as fake news, conspiracy theories, copyright infringement, and hate speech. Commentators have accused Facebook of willingly facilitating the spread of such content, as well as overemphasizing its number of users to appeal to advertisers.

History
The history of Facebook traces its growth from a college networking site to a global social networking service.
While attending Phillips Exeter in the early 2000s, Zuckerberg met Kris Tillery. Tillery, a one-time project collaborator with Zuckerberg, would create a school-based social networking project called Photo Address Book. Photo Address Book was a digital face book, created through a linked database composed of student information derived from the official records of the Exeter Student Council. The database contained linkages such as name, dorm-specific landline numbers, and student headshots.
Mark Zuckerberg built a website called "Facemash" in 2003 while attending Harvard University. The site was comparable to Hot or Not and used photos from online face books, asking users to choose the 'hotter' person". Zuckerberg was reported and faced expulsion, but the charges were dropped.
A "face book" is a student directory featuring photos and personal information. In January 2004, Zuckerberg coded a new site known as "TheFacebook", stating, "It is clear that the technology needed to create a centralized Website is readily available ... the benefits are many." Zuckerberg met with Harvard student Eduardo Saverin, and each agreed to invest $1,000. On February 4, 2004, Zuckerberg launched "TheFacebook".
Membership was initially restricted to students of Harvard College. Dustin Moskovitz, Andrew McCollum, and Chris Hughes joined Zuckerberg to help manage the growth of the site. It became available successively to most universities in the US and Canada. In 2004, Napster co-founder Sean Parker became company president and the company moved to Palo Alto, California. PayPal co-founder Peter Thiel gave Facebook its first investment. In 2005, the company dropped "the" from its name after purchasing the domain name Facebook.com.
In 2006, Facebook opened to everyone at least or only 13 years old with a valid email address. Facebook introduced key features like the News Feed, which became central to user engagement. By late 2007, Facebook had 100,000 pages on which companies promoted themselves. Facebook had surpassed MySpace in global traffic and became the world's most popular social media platform. Microsoft announced that it had purchased a 1.6% share of Facebook for $240 million ($373 million in 2025 dollars), giving Facebook an implied value of around $15 billion ($23.3 billion in 2025 dollars). Facebook focused on generating revenue through targeted advertising based on user data, a model that drove its rapid financial growth. In 2012, Facebook went public with one of the largest IPOs in tech history. Acquisitions played a significant role in Facebook's dominance. In 2012, it purchased Instagram, followed by WhatsApp and Oculus VR in 2014, extending its influence beyond social networking into messaging and virtual reality.
Features
Facebook does not officially publish a maximum character limit for posts; however, user posts can be lengthy, with unofficial sources suggesting a high character limit. Posts may also include images and videos. According to Facebook's official business documentation, videos can be up to 240 minutes long and 10 GB in file size, with supported resolutions up to 1080p.
Users can "friend" users, both sides must agree to being friends. Posts can be changed to be seen by everyone (public), friends, people in a certain group (group) or by selected friends (private). Users can join groups. Groups are composed of persons with shared interests. For example, they might go to the same sporting club, live in the same suburb, have the same breed of pet or share a hobby. Posts posted in a group can be seen only by those in a group, unless set to public.
Users are able to buy, sell, and swap things on Facebook Marketplace or in a Buy, Swap and Sell group. Facebook users may advertise events, which can be offline, on a website other than Facebook, or on Facebook.
Website
Technical aspects
The site's primary color is blue as Zuckerberg is red–green colorblind, a realization that occurred after a test taken around 2007. Facebook was initially built using PHP, a popular scripting language designed for web development. PHP was used to create dynamic content and manage data on the server side of the Facebook application. Zuckerberg and co-founders chose PHP for its simplicity and ease of use, which allowed them to quickly develop and deploy the initial version of Facebook. As Facebook grew in user base and functionality, the company encountered scalability and performance challenges with PHP. In response, Facebook engineers developed tools and technologies to optimize PHP performance. One of the most significant was the creation of the HipHop Virtual Machine (HHVM). This significantly improved the performance and efficiency of PHP code execution on Facebook's servers.
In a 2024 interview with Tiffany Janzen, Zuckerberg stated that if he were to rebuild Facebook using a different language, he'd use Python.
Facebook introduced an option to use the more secure HTTPS instead of HTTP in January 2011, and began making HTTPS the default for all users in November 2012, completing the site-wide switch in 2013.
Facebook is developed as one monolithic application. According to an interview in 2012 with Facebook build engineer Chuck Rossi, Facebook compiles into a 1.5 GB binary blob which is then distributed to the servers using a custom BitTorrent-based release system. Rossi stated that it takes about 15 minutes to build and 15 minutes to release to the servers. The build and release process has zero downtime. Changes to Facebook are rolled out daily.
Facebook used a combination platform based on HBase to store data across distributed machines. Using a tailing architecture, events are stored in log files, and the logs are tailed. The system rolls these events up and writes them to storage. The user interface then pulls the data out and displays it to users. Facebook handles requests as AJAX behavior. These requests are written to a log file using Scribe (developed by Facebook).
Data is read from these log files using Ptail, an internally built tool to aggregate data from multiple Scribe stores. It tails the log files and pulls data out. Ptail data are separated into three streams and sent to clusters in different data centers (Plugin impression, News feed impressions, Actions (plugin + news feed)). Puma is used to manage periods of high data flow (Input/Output or IO). Data is processed in batches to lessen the number of times needed to read and write under high demand periods. (A hot article generates many impressions and news feed impressions that cause huge data skews.) Batches are taken every 1.5 seconds, limited by memory used when creating a hash table.
User profile/personal timeline
Each registered user on Facebook has a personal profile that shows their posts and content. The format of individual user pages was revamped in September 2011 and became known as "Timeline", a chronological feed of a user's stories, including status updates, photos, interactions with apps and events. The layout let users add a "cover photo". Users were given more privacy settings. In 2007, Facebook launched Facebook Pages for brands and celebrities to interact with their fanbases. In June 2009, Facebook introduced a "Usernames" feature, allowing users to choose a unique nickname used in the URL for their personal profile, for easier sharing.
In February 2014, Facebook expanded the gender setting, adding a custom input field that allows users to choose from a wide range of gender identities. Users can also set which set of gender-specific pronoun should be used in reference to them throughout the site. In May 2014, Facebook introduced a feature to allow users to ask for information not disclosed by other users on their profiles. If a user does not provide key information, such as location, hometown, or relationship status, other users can use a new "ask" button to send a message asking about that item to the user in a single click.
News Feed
News Feed appears on every user's homepage and highlights information including profile changes, upcoming events and friends' birthdays. This enabled spammers and other users to manipulate these features by creating illegitimate events or posting fake birthdays to attract attention to their profile or cause. Another issue is that the birthday of Leap-Day babies (those born on February 29 in leap years) is neglected three years out of four, along with memories of that day. Initially, the News Feed caused dissatisfaction among Facebook users; some complained it was too cluttered and full of undesired information, others were concerned that it made it too easy for others to track individual activities (such as relationship status changes, events, and conversations with other users). Zuckerberg apologized for the site's failure to include appropriate privacy features. Users then gained control over what types of information are shared automatically with friends. Users are now able to prevent user-set categories of friends from seeing updates about certain types of activities, including profile changes, Wall posts and newly added friends.
On February 23, 2010, Facebook was granted a patent on certain aspects of its News Feed. The patent covers News Feeds in which links are provided so that one user can participate in the activity of another user. The sorting and display of stories in a user's News Feed is governed by the EdgeRank algorithm. The Photos application allows users to upload albums and photos. Each album can contain 200 photos. Privacy settings apply to individual albums. Users can "tag", or label, friends in a photo. The friend receives a notification about the tag with a link to the photo. This photo tagging feature was developed by Aaron Sittig, now a Design Strategy Lead at Facebook, and former Facebook engineer Scott Marlette back in 2006 and was only granted a patent in 2011.
On June 7, 2012, Facebook launched its App Center to help users find games and other applications.
On May 13, 2015, Facebook in association with major news portals launched "Instant Articles" to provide news on the Facebook news feed without leaving the site. In January 2017, Facebook launched Facebook Stories for iOS and Android in Ireland. The feature, following the format of Snapchat and Instagram stories, allows users to upload photos and videos that appear above friends' and followers' News Feeds and disappear after 24 hours.
Like button
The "like" button, stylized as a "thumbs up" icon, was first enabled on February 9, 2009, and enables users to easily interact with status updates, comments, photos and videos, links shared by friends, and advertisements. Once clicked by a user, the designated content is more likely to appear in friends' News Feeds. The button displays the number of other users who have liked the content. The like button was extended to comments in June 2010. In February 2016, Facebook expanded Like into "Reactions", allowing users to choose from five pre-defined emotions: "Love", "Haha", "Wow", "Sad", or "Angry". In late April 2020, during the COVID-19 pandemic, a new "Care" reaction was added.
Instant messaging
Facebook Messenger is an instant messaging service and software application. It began as Facebook Chat in 2008, was revamped in 2010 and eventually became a standalone mobile app in August 2011, while remaining part of the user page on browsers. Complementing regular conversations, Messenger lets users make one-to-one and group voice and video calls. Its Android app has integrated support for SMS and "Chat Heads", which are round profile photo icons appearing on-screen regardless of what app is open, while both apps support multiple accounts, conversations with optional end-to-end encryption and "Instant Games". Some features, including sending money and requesting transportation, are limited to the United States. In 2017, Facebook added "Messenger Day", a feature that lets users share photos and videos in a story-format with all their friends with the content disappearing after 24 hours; Reactions, which lets users tap and hold a message to add a reaction through an emoji; and Mentions, which lets users in group conversations type @ to give a particular user a notification.
In April 2020, Facebook began rolling out a new feature called Messenger Rooms, a video chat feature that allows users to chat with up to 50 people at a time. In July 2020, Facebook added a new feature in Messenger that lets iOS users to use Face ID or Touch ID to lock their chats. The feature is called App Lock and is a part of several changes in Messenger regarding privacy and security. On October 13, 2020, the Messenger application introduced cross-app messaging with Instagram, which was launched in September 2021. In addition to the integrated messaging, the application announced the introduction of a new logo, which will be an amalgamation of the Messenger and Instagram logo.
Businesses and users can interact through Messenger with features such as tracking purchases and receiving notifications, and interacting with customer service representatives. Third-party developers can integrate apps into Messenger, letting users enter an app while inside Messenger and optionally share details from the app into a chat. Developers can build chatbots into Messenger, for uses such as news publishers building bots to distribute news. Businesses like respond.io, Twilio, and Manychat also used the APIs to develop chatbots and automation platforms for commercial use.
The M virtual assistant (U.S.) scans chats for keywords and suggests relevant actions, such as its payments system for users mentioning money. Group chatbots appear in Messenger as "Chat Extensions". A "Discovery" tab allows finding bots, and enabling special, branded QR codes that, when scanned, take the user to a specific bot.
Privacy policy
Facebook's data policy outlines its policies for collecting, storing, and sharing user's data. Facebook enables users to control access to individual posts and their profile through privacy settings. The user's name and profile picture (if applicable) are public.
Facebook's revenue depends on targeted advertising, which involves analyzing user data to decide which ads to show each user. Facebook buys data from third parties, gathered from both online and offline sources, to supplement its own data on users. Facebook maintains that it does not share data used for targeted advertising with the advertisers themselves. The company states:
"We provide advertisers with reports about the kinds of people seeing their ads and how their ads are performing, but we don't share information that personally identifies you (information such as your name or email address that by itself can be used to contact you or identifies who you are) unless you give us permission. For example, we provide general demographic and interest information to advertisers (for example, that an ad was seen by a woman between the ages of 25 and 34 who lives in Madrid and likes software engineering) to help them better understand their audience. We also confirm which Facebook ads led you to make a purchase or take an action with an advertiser."
As of October 2021, Facebook claims it uses the following policy for sharing user data with third parties:
Apps, websites, and third-party integrations on or using our Products.
When you choose to use third-party apps, websites, or other services that use, or are integrated with, our Products, they can receive information about what you post or share. For example, when you play a game with your Facebook friends or use a Facebook Comment or Share button on a website, the game developer or website can receive information about your activities in the game or receive a comment or link that you share from the website on Facebook. Also, when you download or use such third-party services, they can access your public profile on Facebook, and any information that you share with them. Apps and websites you use may receive your list of Facebook friends if you choose to share it with them. But apps and websites you use will not be able to receive any other information about your Facebook friends from you, or information about any of your Instagram followers (although your friends and followers may, of course, choose to share this information themselves). Information collected by these third-party services is subject to their own terms and policies, not this one.
Bug Bounty Program
On July 29, 2011, Facebook announced its Bug Bounty Program that paid security researchers a minimum of $500 ($716.00 in 2025 dollars) for reporting security holes. The company promised not to pursue "white hat" hackers who identified such problems. This led researchers in many countries to participate, particularly in India and Russia.
Reception
Userbase
Facebook's rapid growth began as soon as it became available and continued through 2018, before beginning to decline. Facebook passed 100 million registered users in 2008, and 500 million in July 2010. According to the company's data at the July 2010 announcement, half of the site's membership used Facebook daily, for an average of 34 minutes, while 150 million users accessed the site by mobile.
In October 2012, Facebook's monthly active users passed one billion, with 600 million mobile users, 219 billion photo uploads, and 140 billion friend connections. The 2 billion user mark was crossed in June 2017. In November 2015, after skepticism about the accuracy of its "monthly active users" measurement, Facebook changed its definition to a logged-in member who visits the Facebook site through the web browser or mobile app, or uses the Facebook Messenger app, in the 30-day period prior to the measurement. This excluded the use of third-party services with Facebook integration, which was previously counted.
From 2017 to 2019, the percentage of the U.S. population over the age of 12 who use Facebook has declined, from 67% to 61% (a decline of some 15 million U.S. users), with a higher drop-off among younger Americans (a decrease in the percentage of U.S. 12- to 34-year-olds who are users from 58% in 2015 to 29% in 2019). The decline coincided with an increase in the popularity of Instagram, which is also owned by Meta. The number of daily active users experienced a quarterly decline for the first time in the last quarter of 2021, down to 1.929 billion from 1.930 billion, but increased again the next quarter despite being banned in Russia.
Historically, commentators have offered predictions of Facebook's decline or end, based on causes such as a declining user base; the legal difficulties of being a closed platform, inability to generate revenue, inability to offer user privacy, inability to adapt to mobile platforms, or Facebook ending itself to present a next generation replacement; or Facebook's role in Russian interference in the 2016 United States elections.
Demographics
The highest number of Facebook users as of April 2023 are from India and the United States, followed by Indonesia, Brazil, Mexico and the Philippines. Region-wise, the highest number of users in 2018 are from Asia-Pacific (947 million) followed by Europe (381 million) and US-Canada (242 million). The rest of the world has 750 million users.
Over the 2008–2018 period, the percentage of users under 34 declined to less than half of the total.
Censorship
In many countries the social networking sites and mobile apps have been blocked temporarily, intermittently, or permanently, including: Brazil, China, Iran, Vietnam, Pakistanc, Syria, and North Korea. In May 2018, the government of Papua New Guinea announced that it would ban Facebook for a month while it evaluated the website's impact on the country, though no ban has since occurred. In 2019, Facebook announced it would start enforcing its ban on users, including influencers, promoting any vape, tobacco products, or weapons on its platforms.
Criticisms and controversies
Facebook's importance and scale has led to criticisms in many domains. Issues include Internet privacy, excessive retention of user information, its facial recognition software, DeepFace its addictive quality and its role in the workplace, including employer access to employee accounts.
Facebook has been criticized for electricity usage, tax avoidance, real-name user requirement policies, censorship and its involvement in the United States PRISM surveillance program. According to The Express Tribune, Facebook "avoided billions of dollars in tax using offshore companies".
Facebook is alleged to have harmful psychological effects on its users, including feelings of jealousy and stress, a lack of attention and social media addiction. According to Kaufmann et al., mothers' motivations for using social media are often related to their social and mental health. European antitrust regulator Margrethe Vestager stated that Facebook's terms of service relating to private data were "unbalanced".
Facebook has been criticized for allowing users to publish illegal or offensive material. Specifics include copyright and intellectual property infringement, hate speech, incitement of rape and terrorism, fake news, and crimes, murders, and livestreaming violent incidents. Commentators have accused Facebook of willingly facilitating the spread of such content. Sri Lanka blocked both Facebook and WhatsApp in May 2019 after anti-Muslim riots, the worst in the country since the Easter Sunday bombing in the same year as a temporary measure to maintain peace in Sri Lanka.
Facebook removed 3 billion fake accounts only during the last quarter of 2018 and the first quarter of 2019; in comparison, the social network reports 2.39 billion monthly active users.
In late July 2019, the company announced it was under antitrust investigation by the Federal Trade Commission.
The consumer advocacy group Which? claimed individuals were still utilizing Facebook to set up fraudulent five-star ratings for products. The group identified 14 communities that exchange reviews for either money or complimentary items such as watches, earbuds, and sprinklers.
Privacy concerns
Facebook has experienced a steady stream of controversies over how it handles user privacy, repeatedly adjusting its privacy settings and policies. Since 2009, Facebook has been participating in the PRISM secret program, sharing with the US National Security Agency audio, video, photographs, e-mails, documents and connection logs from user profiles, among other social media services.
On November 29, 2011, Facebook settled Federal Trade Commission charges that it deceived consumers by failing to keep privacy promises. In August 2013 High-Tech Bridge published a study showing that links included in Facebook messaging service messages were being accessed by Facebook. In January 2014 two users filed a lawsuit against Facebook alleging that their privacy had been violated by this practice.
On June 7, 2018, Facebook announced that a bug had resulted in about 14 million Facebook users having their default sharing setting for all new posts set to "public". Its data-sharing agreement with Chinese companies such as Huawei came under the scrutiny of US lawmakers, although the information accessed was not stored on Huawei servers and remained on users' phones. On April 4, 2019, half a billion records of Facebook users were found exposed on Amazon cloud servers, containing information about users' friends, likes, groups, and checked-in locations, as well as names, passwords and email addresses.
The phone numbers of at least 200 million Facebook users were found to be exposed on an open online database in September 2019. They included 133 million US users, 18 million from the UK, and 50 million from users in Vietnam. After removing duplicates, the 419 million records have been reduced to 219 million. The database went offline after TechCrunch contacted the web host. It is thought the records were amassed using a tool that Facebook disabled in April 2018 after the Cambridge Analytica controversy. A Facebook spokeswoman said in a statement: "The dataset is old and appears to have information obtained before we made changes last year...There is no evidence that Facebook accounts were compromised."
Facebook's privacy problems resulted in companies like Viber Media and Mozilla discontinuing advertising on Facebook's platforms. A January 2024 study by Consumer Reports found that among a self-selected group of volunteer participants, each user is monitored or tracked by over two thousand companies on average. LiveRamp, a San Francisco-based data broker, is responsible for 96 per cent of the data. Other companies such as Home Depot, Macy's, and Walmart are involved as well.
Content disputes and moderation
Facebook relies on its users to generate the content that bonds its users to the service. The company has come under criticism both for allowing objectionable content, including conspiracy theories and fringe discourse, and for prohibiting other content that it deems inappropriate.
Facebook has been criticized as a vector for fake news, and has been accused of bearing responsibility for the conspiracy theory that the United States created ISIS, false anti-Rohingya posts being used by Myanmar's military to fuel genocide and ethnic cleansing, enabling climate change denial and Sandy Hook Elementary School shooting conspiracy theorists, and anti-refugee attacks in Germany. The government of the Philippines has also used Facebook as a tool to attack its critics.
In 2017, Facebook partnered with fact checkers from the Poynter Institute's international fact-checking network to identify and mark false content, though most ads from political candidates are exempt from this program. As of 2018, Facebook had over 40 fact-checking partners across the world, including The Weekly Standard. Critics of the program have accused Facebook of not doing enough to remove false information from its website.
Facebook has repeatedly amended its content policies. In July 2018, it stated that it would "downrank" articles that its fact-checkers determined to be false, and remove misinformation that incited violence. Facebook stated that content that receives "false" ratings from its fact-checkers can be demonetized and suffer dramatically reduced distribution. Specific posts and videos that violate community standards can be removed on Facebook. In May 2019, Facebook banned a number of "dangerous" commentators from its platform, including Alex Jones, Louis Farrakhan, Milo Yiannopoulos, Paul Joseph Watson, Paul Nehlen, David Duke, and Laura Loomer, for allegedly engaging in "violence and hate".
In May 2020, Facebook agreed to a preliminary settlement of $52 million ($64.7 million in 2025 dollars) to compensate U.S.-based Facebook content moderators for their psychological trauma suffered on the job. Other legal actions around the world, including in Ireland, await settlement. In September 2020, the Government of Thailand utilized the Computer Crime Act for the first time to take action against Facebook and Twitter for ignoring requests to take down content and not complying with court orders.
Political manipulation
As a dominant social-web service with massive outreach, Facebook has been used by identified or unidentified political operatives to affect public opinion. Some of these activities have been done in violation of the platform policies, creating "coordinated inauthentic behavior", support or attacks. These activities can be scripted or paid. Various such abusive campaign have been revealed in recent years, best known being the Russian interference in the 2016 United States elections. In 2021, former Facebook analyst within the Spam and Fake Engagement teams, Sophie Zhang, reported more than 25 political subversion operations and criticized the general slow reaction time, oversightless, laissez-faire attitude by Facebook.
In 2018, Facebook said that during 2018 they had identified "coordinated inauthentic behavior" in "many Pages, Groups and accounts created to stir up political debate, including in the US, the Middle East, Russia and the UK."
Campaigns operated by the British intelligence agency unit, called Joint Threat Research Intelligence Group, have broadly fallen into two categories; cyber attacks and propaganda efforts. The propaganda efforts utilize "mass messaging" and the "pushing [of] stories" via social media sites like Facebook. Israel's Jewish Internet Defense Force, the Chinese Communist Party's 50 Cent Party and Turkey's AK Trolls also focus their attention on social media platforms like Facebook. In July 2018, Samantha Bradshaw, co-author of the report from the Oxford Internet Institute (OII) at Oxford University, said that "The number of countries where formally organised social media manipulation occurs has greatly increased, from 28 to 48 countries globally. The majority of growth comes from political parties who spread disinformation and junk news around election periods." In October 2018, The Daily Telegraph reported that Facebook "banned hundreds of pages and accounts that it says were fraudulently flooding its site with partisan political content – although they came from the United States instead of being associated with Russia."
In December 2018, The Washington Post reported that "Facebook has suspended the account of Jonathon Morgan, the chief executive of a top social media research firm" New Knowledge, "after reports that he and others engaged in an operation to spread disinformation" on Facebook and Twitter during the 2017 United States Senate special election in Alabama. In January 2019, Facebook said it has removed 783 Iran-linked accounts, pages and groups for engaging in what it called "coordinated inauthentic behaviour". In March 2019, Facebook sued four Chinese firms for selling "fake accounts, likes and followers" to amplify Chinese state media outlets.
Company governance
Early Facebook investor and former Zuckerberg mentor Roger McNamee described Facebook as having "the most centralized decision-making structure I have ever encountered in a large company." Nathan Schneider, a professor of media studies at the University of Colorado Boulder argued in 2018 for transforming Facebook into a platform cooperative owned and governed by the users.
Facebook co-founder Chris Hughes stated in 2019 that CEO Mark Zuckerberg has too much power, that the company is now a monopoly, and that, as a result, it should be split into multiple smaller companies. He called for the breakup of Facebook in an op-ed in The New York Times. Hughes says he is concerned that Zuckerberg has surrounded himself with a team that does not challenge him and that as a result, it is the U.S. government's job to hold him accountable and curb his "unchecked power". Hughes also said that "Mark's power is unprecedented and un-American." Several U.S. politicians agree with Hughes. EU Commissioner for Competition Margrethe Vestager has stated that splitting Facebook should only be done as "a remedy of the very last resort", and that splitting Facebook would not solve Facebook's underlying problems.
Customer support
Facebook has been criticized for its lack of human customer support. When users personal and business accounts are breached, many are forced to go through small claims court to regain access and restitution.
Litigation
The company has been subject to repeated litigation. Its most prominent case addressed allegations that Zuckerberg broke an oral contract with Cameron Winklevoss, Tyler Winklevoss, and Divya Narendra to build the then-named "HarvardConnection" social network in 2004.
On March 6, 2018, BlackBerry sued Facebook and its Instagram and WhatsApp subdivision for ripping off key features of its messaging app. In October 2018, a Texan woman sued Facebook, claiming she had been recruited into the sex trade at the age of 15 by a man who "friended" her on the social media network. Facebook responded that it works both internally and externally to ban sex traffickers.
In 2019, British solicitors representing a bullied Syrian schoolboy, sued Facebook over false claims. They claimed that Facebook protected prominent figures from scrutiny instead of removing content that violates its rules and that the special treatment was financially driven. The Federal Trade Commission and a coalition of New York state and 47 other state and regional governments filed separate suits against Facebook on December 9, 2020, seeking antitrust action based on its acquisitions of Instagram and WhatsUp among other companies, calling these practices as anticompetitive. The suits also assert that in acquiring these products, they weakened their privacy measures for their users. The suits, besides other fines, seek to unwind the acquisitions from Facebook.
On January 6, 2022, France's data privacy regulatory body CNIL fined Facebook a 60 million euros for not allowing its internet users an easy refusal of cookies along with Google. On December 22, 2022, the Quebec Court of Appeal approved a class-action lawsuit on behalf of Facebook users who claim they were discriminated against because the platform allows advertisers to target both job and housing advertisements based on various factors, including age, gender, and even race. The lawsuit centers on the platform's practice of "micro targeting ads", claiming ads are ensured to appear only in the feeds of people who belong to certain targeted groups. Women, for example, would not see ads targeting men, while older generation men would not see an ad aimed at people between 18 and 45.
The class action could include thousands of Quebec residents who have been using the platform as early as April 2016, who were seeking jobs or housing during that period. Facebook has 60 days after the court's December 22 ruling to decide to appeal the case to the Supreme Court of Canada. If it does not appeal, the case returns to the Quebec Superior Court. On September 21, 2023, the California Courts of Appeal ruled that Facebook could be sued for discriminatory advertising under the Unruh Civil Rights Act.
Impact
Scope
A commentator in The Washington Post noted in 2019 that Facebook constitutes a "massive depository of information that documents both our reactions to events and our evolving customs with a scope and immediacy of which earlier historians could only dream". Especially for anthropologists, social researchers, and social historians—and subject to proper preservation and curation—the website "will preserve images of our lives that are vastly crisper and more nuanced than any ancestry record in existence".
Economy
Economists have noted that Facebook offers many non-rivalrous services that benefit as many users as are interested without forcing users to compete with each other. By contrast, most goods are available to a limited number of users. E.g., if one user buys a phone, no other user can buy that phone. Three areas add the most economic impact: platform competition, the market place and user behavior data. Facebook began to reduce its carbon impact after Greenpeace attacked it for its long-term reliance on coal and resulting carbon footprint. In 2021 Facebook announced that their global operations are supported by 100 percent renewable energy and they have reached net zero emissions, a goal set in 2018.
Facebook provides a development platform for many social gaming, communication, feedback, review, and other applications related to online activities. This platform spawned many businesses and added thousands of jobs to the global economy. Zynga Inc., a leader in social gaming, is an example of such a business. An econometric analysis found that Facebook's app development platform added more than 182,000 jobs in the U.S. economy in 2011. The total economic value of the added employment was about $12 billion ($17.2 billion in 2025 dollars).
Society
Facebook was one of the first large-scale social networks. In The Facebook Effect, David Kirkpatrick said that Facebook's structure makes it difficult to replace, because of its "network effects". As of 2016, it was estimated 44% of Americans get news through Facebook. A study published at Frontiers Media in 2023 found that there was more polarization of the user-base on Facebook than even far-right social networks like Gab.
Mental and emotional health
Studies have associated social networks with positive and negative impacts on emotional health.
Studies have associated Facebook with feelings of envy, often triggered by vacation and holiday photos. Other triggers include posts by friends about family happiness and images of physical beauty—such feelings leave people dissatisfied with their own lives. A joint study by two German universities discovered that one out of three people were more dissatisfied with their lives after visiting Facebook, and another study by Utah Valley University found that college students felt worse about themselves following an increase in time on Facebook.
Positive effects include signs of "virtual empathy" with online friends and helping introverted persons learn social skills. A 2020 experimental study in the American Economic Review found that deactivating Facebook led to increased subjective well-being. In a blog post in December 2017, the company highlighted research that has shown "passively consuming" the News Feed, as in reading but not interacting, left users with negative feelings, whereas interacting with messages pointed to improvements in well-being.
Politics
In February 2008, a Facebook group called "One Million Voices Against FARC" organized an event in which hundreds of thousands of Colombians marched in protest against the Revolutionary Armed Forces of Colombia (FARC). In August 2010, one of North Korea's official government websites and the country's official news agency, Uriminzokkiri, joined Facebook.
During the Arab Spring many journalists claimed Facebook played a major role in the 2011 Egyptian revolution. On January 14, the Facebook page of "We are all Khaled Said" was started by Wael Ghoniem to invite the Egyptian people to "peaceful demonstrations" on January 25. In Tunisia and Egypt, Facebook became the primary tool for connecting protesters and led the Egyptian government to ban it, Twitter and other sites. After 18 days, the uprising forced President Hosni Mubarak to resign.
In a Bahraini uprising that started on February 14, 2011, Facebook was utilized by the Bahraini regime and regime loyalists to identify, capture and prosecute citizens involved in the protests. A 20-year-old woman named Ayat Al Qurmezi was identified as a protester using Facebook and imprisoned. In 2011, Facebook filed paperwork with the Federal Election Commission to form a political action committee under the name FB PAC. In an email to The Hill, a spokesman for Facebook said "Facebook Political Action Committee will give our employees a way to make their voice heard in the political process by supporting candidates who share our goals of promoting the value of innovation to our economy while giving people the power to share and make the world more open and connected."
During the Syrian civil war, the YPG, a libertarian army for Rojava recruited westerners through Facebook in its fight against ISIL. Dozens joined its ranks. The Facebook page's name "The Lions of Rojava" comes from a Kurdish saying which translates as "A lion is a lion, whether it's a female or a male", reflecting the organization's feminist ideology.
In recent years, Facebook's News Feed algorithms have been identified as a cause of political polarization, for which it has been criticized. It has likewise been accused of amplifying the reach of 'fake news' and extreme viewpoints, as when it may have enabled conditions which led to the 2015 Rohingya refugee crisis. Facebook first played a role in the American political process in January 2008, shortly before the New Hampshire primary. Facebook teamed up with ABC and Saint Anselm College to allow users to give live feedback about the "back to back" January 5 Republican and Democratic debates. Facebook users took part in debate groups on specific topics, voter registration and message questions.
Culture
Facebook and Zuckerberg have been the subject of music, books, film and television. The 2010 film The Social Network, directed by David Fincher and written by Aaron Sorkin, stars Jesse Eisenberg as Zuckerberg and went on to win three Academy Awards and four Golden Globes.
In 2008, Collins English Dictionary declared "Facebook" as its new Word of the Year. In December 2009, the New Oxford American Dictionary declared its word of the year to be the verb "unfriend", defined as "To remove someone as a 'friend' on a social networking site such as Facebook".
Internet.org
In August 2013, Facebook founded Internet.org in collaboration with six other technology companies to plan and help build affordable Internet access for underdeveloped and developing countries. The service, called Free Basics, includes various low-bandwidth applications such as AccuWeather, BabyCenter, BBC News, ESPN, and Bing. There was severe opposition to Internet.org in India, where the service started in partnership with Reliance Communications in 2015 was banned a year later by the Telecom Regulatory Authority of India (TRAI). In 2018, Zuckerberg claimed that "Internet.org efforts have helped almost 100 million people get access to the internet who may not have had it otherwise."
Environment
Facebook announced in 2021 that it will make an effort to stop disinformation about climate change. The company will use George Mason University, Yale Program on Climate Change Communication and the University of Cambridge as sources of information. The company will expand its information hub on climate to 16 countries. Users in other countries will be directed to the site of the United Nations Environment Programme for information.
