Why is The Big Bang Theory ending? Jim Parsons was ready to say goodbye to Sheldon Cooper.
A source told E! News that Parsons, who won four Emmys and a Golden Globe for playing the Big Bang physicist, was ready to explore life and more work outside the series. Parsons recently wrapped a run on Broadway in the Ryan Murphy-produced The Boys in the Band and our source said it was his summer on stage that helped fuel his decision to exit, however it wasn't a hastily made decision, it was something Parsons has been debating for months. We're told Parsons is happy the show is ending while still a hit and creatively successful.
