The French Connection

The fourth and final season of The O.C., an American teen drama television series, aired in the United States from November 2, 2006, to February 22, 2007, and consisted of 16 episodes. The O.C.'s final season aired Thursdays at 9:00 p.m. ET in the United States on Fox, a terrestrial television network. Fox tested a new timeslot by airing the second episode on Wednesday at 9:00 p.m. ET against ABC's Lost and CBS's Criminal Minds. With Lost about to enter a three-month hiatus, Fox hoped that changing the timeslot for The O.C. would attract back viewers it had lost since the end of the previous season; however, the move was unsuccessful and the show returned to its Thursday timeslot.
