"The Big Bang Theory" was on the air for an impressive 12 seasons, ending in 2019. The comedy stars Jim Parsons, Johnny Galecki, Kaley Cuoco, Simon Helberg, and Kunal Nayyar, and takes place in Pasadena, California. Cuoco's character, Penny, is an aspiring actress who moves next door to a group of socially awkward scientists, befriending them with often hilarious results.
The breakout character of the show is Parsons' Sheldon Cooper, a neurotic and quirky individual who often clashes with Penny. Parsons has won four Emmy Awards (and has been nominated 65 times across various awards for his performance) and a Golden Globe for his role, while the show itself has picked up a whopping 46 Emmy noms altogether. A spin-off prequel, "Young Sheldon," centered on a younger version of Cooper, debuted in 2017.
