The Real Reason Why The Big Bang Theory Ended

While Parsons's decision ultimately led to the show's demise, and producer Chuck Lorre decided no Big Bang was preferable to a Sheldon-free Big Bang, and cast members Johnny Galecki, Kaley Cuoco, and Mayim Bialik became publicly wistful, no one (as of yet) has seemed particularly angry about the fact that they all lost their jobs. Why? Well, they all pulled in huge paychecks for their work on the show, but perhaps it's also because they know that the writing was on the wall of the writers' room.

Nearly 300 episodes of The Big Bang Theory were produced, which is a lot of time and space to explore a handful of characters. There isn't a lot more for Sheldon, Leonard, Penny, Raj, Howard, Bernadette, and Amy to do. They all (mostly) evolved from young, single, immature scientists into middle-aged, married people with children and numerous major career milestones to their credit. Their arcs were basically complete, so there wasn't much more for Big Bang writers to say. 

Heck, even the elevator finally got fixed.
