On January 7, 2011, the cable channel History announced that it would not show The Kennedys in the United States, stating "this dramatic interpretation is not a fit for the History brand."
Michael Prupas, president of Muse Entertainment and executive producer of the miniseries, issued a statement on January 10, in which he addressed the claims of inaccuracies: "The decision of the History Channel not to broadcast the show was made long after the executives of the Channel as well as the Channel's resident historian (who is a Kennedy expert) had read and approved all of the scripts and viewed and approved all of the final cuts of all of the episodes. Furthermore, our Errors and Omissions Insurer's attorneys reviewed all the scripts and edited episodes – and they have cleared all of the episodes for broadcast."
Director Jon Cassar said at the January 2011 Television Critics Association gathering in Los Angeles that he believed the reason the miniseries would not be shown by History and other US broadcasters was because powerful people within the United States connected to the Kennedy family took exception to it and used their political and other influence to prevent the showing.
Joel Surnow, the series' executive producer, attributed the cancellation to pressure exerted by the Kennedys on the board of History's owners, A&E Television Networks and The Walt Disney Company. Surnow stated: "It happened at the board level. I don't want to mention anyone by name. It's very simple to say that certain board members are friends with the Kennedys." Other reports pinpointed Kennedy family members Maria Shriver and Caroline Kennedy as the leaders of the campaign to stop the show, targeting Disney executive Anne Sweeney.
On January 12, Showtime passed on the US broadcasting rights for The Kennedys. Two days later, it was reported that DirecTV's The 101 Network was considering acquiring the miniseries. On January 24, it was announced that The 101 Network also passed on airing the show. Eight days later, ReelzChannel acquired US broadcast rights to The Kennedys and announced their intention to show the miniseries between April 3 and 10, 2011. Other US cable channels reported to have declined acquisition of the miniseries are FX and Starz.
Mediaweek reported that Hubbard Broadcasting, the owners of ReelzChannel, took a big risk in purchasing the rights to the miniseries by paying an estimated $7 million for the broadcast rights and spending an additional $10 million in advertising.
