Chuck is an American action comedy spy drama television series created by Josh Schwartz and Chris Fedak. The series is about an "average computer-whiz-next-door" named Chuck Bartowski, played by Zachary Levi, who receives an encoded email from an old college friend now working for the CIA. The message embeds the only remaining copy of a software program containing the United States' greatest spy secrets into Chuck's brain, leading the CIA and the NSA to assign him handlers and use him on top-secret missions. Produced by Fake Empire (known as College Hill Pictures, Inc. during the first three seasons before folding afterwards), Wonderland Sound and Vision, and Warner Bros. Television, the series premiered on September 24, 2007, on NBC, airing on Monday nights at 8:00 p.m./7:00 p.m. Central. The opening theme song is an instrumental version of "Short Skirt/Long Jacket" by the American rock band Cake.

As the second season finished, flagging ratings put Chuck in danger of cancellation, but fans mounted a successful campaign to encourage NBC to renew the show. The campaign was unique in that fans specifically targeted a sponsor of the show, the Subway restaurant chain, leading to the chain striking a major sponsorship deal with NBC to help cover costs of the third season. The series' renewal was uncertain in each subsequent season. The fifth season was the last, beginning on October 28, 2011, and moving to Friday nights at 8 p.m./7 Central. The series concluded on January 27, 2012, with a two-hour finale.
