Philosophising about the 'S'-word: Watch… and learn
The Big Bang Theory is an American sitcom created by Chuck Lorre (Grace Under Fire, Dharma & Greg, Two and a Half Men, Roseanne) and Bill Prady (Gilmore Girls, Dream On, Dharma & Greg), both of whom serve as executive producers on the show along with Steven Molaro (Freddie, All That). All three also serve as head writers. It premiered on September 24th, 2007 on CBS.
The show is centered on five characters living in Pasadena, California: roommates Leonard Hofstadter (Johnny Galecki, Roseanne) and Sheldon Cooper (Jim Parsons, Judging Amy), both physicists; Penny (Kaley Cuoco, 8 Simple Rules, Charmed), a waitress and aspiring actress who lives across the hall; and Leonard and Sheldon’s equally geeky and socially awkward friends and co-workers, mechanical engineer Howard Wolowitz (Simon Helberg, Joey, Studio 60 on the Sunset Strip) and astrophysicist Raj Koothrappali (Kunal Nayyar, Sanjay and Craig). 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 (Sara Gilbert, Roseanne, ER, Twins), a physicist colleague at Caltech and, at different times, a lover of both Leonard and Howard; Bernadette Rostenkowski (Melissa Rauch, Kath & Kim), Howard’s girlfriend (later his wife), a microbiologist and former part-time waitress alongside Penny; neuroscientist Amy Farrah Fowler (Mayim Bialik, Blossom), who joins the group after being matched to Sheldon on a dating website (and later becomes Sheldon’s girlfriend), and Stuart Bloom (Kevin Sussman, Ugly Betty, Weeds), the cash-strapped owner of the comic book store the characters often visit.
