Big Bang Theory, the

The Big Bang Theory is an American sitcom created by Chuck Lorre and Bill Prady, both of whom serve as executive producers on the show along with Steven Molaro. All three also serve as head writers. It premiered on CBS on September 24, 2007. The eighth season premiered on September 22, 2014.

The show is primarily centered on five characters living in Pasadena, California: roommates Leonard Hofstadter and Sheldon Cooper, both physicists; Penny, a waitress and aspiring actress who later becomes a pharmaceutical representative, who lives across the hall; and Leonard and Sheldon's equally geeky and socially awkward friends and co-workers, aerospace engineer Howard Wolowitz and astrophysicist Raj Koothrappali. The geekiness and intellect of the four guys is contrasted for comic effect with Penny's social skills and common sense.

Over time, supporting characters have been promoted to starring roles: Leslie Winkle, a physicist colleague at California Institute of Technology and a former lover to each of Leonard and Howard; Bernadette Rostenkowski, Howard's girlfriend (later his wife), a microbiologist and former part-time waitress alongside Penny; neuroscientist Amy Farrah Fowler, who joins the group after being matched to Sheldon on a dating website (and later becomes Sheldon's girlfriend); and Stuart Bloom, the cash-strapped owner of the comic book store the characters often visit, who, in Season 8, moves in with Howard's mother.
