The Big Bang Theory is a hugely popular and successful sitcom that people totally adore! It stars Kaley Cuoco, Jim Parsons, Johnny Galecki, and Mayim Bialik. The first episode of The Big Bang Theory aired on September 24, 2007, and the final episode aired on May 16, 2019. That is a lot of years worth of episodes! In fact, this show ran for twelve seasons and has a total of 279 episodes!
This show ran longer than Friends which only lasted for ten seasons and The Office which only ran for nine seasons. CBS is the network that made The Big Bang Theory possible and as of now, it has one spin-off titled Young Sheldon from 2017. We are sure fans would absolutely love to see more spin-offs from this show! Check out some interesting photos of the cast of The Big Bang Theory over the years... 2007 to 2019!
