About The Big Bang Theory

The Big Bang Theory (often shortened to Big Bang Theory, and often abbreviated to TBBT or BBT) is an American television sitcom created by Chuck Lorre and Bill Prady, both of them serve as executive producers on the series, along with Steven Molaro. All three as well serve as head writers also. The show premiered on CBS on September 24, 2007. In March 2014, the show was renewed for three more years through a tenth season, which is set to premiere on September 19, 2016.

The show is mainly centered on five characters living in Pasadena, California: Leonard Hofstadter and Sheldon Cooper, both physicists at Caltech, who share an apartment; Penny, a waitress and aspiring actress who later becomes a pharmaceutical representative and who lives across the hall; and Leonard and Sheldon's similarly geeky and publicly awkward friends and co-workers, aerospace engineer Howard Wolowitz and astrophysicist Raj Koothrappali. The geekiness and intellect of the four men is contrasted for comic effect with Penny's public skills and common sense.

Over time, supporting characters have been promoted to starring roles: 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); 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; and Emily Sweeney, a dermatologist who dates Raj and has a fascination with the macabre.
