The nerdy origins: A show born of science and sarcasm
Created by comedy king Chuck Lorre and screenwriter Bill Prady, The Big Bang Theory made its debut on CBS on 24 September 2007 and ran until 16 May 2019. With 12 seasons and a global fanbase, it became one of the most-watched sitcoms of the 21st century.
Set in Pasadena, California, the show revolves around socially awkward geniuses Leonard Hofstadter and Sheldon Cooper—both physicists at Caltech—and their attempts to make sense of everyday life, dating, and pop culture.
