Big bang, that's how it all began! The Big Bang Theory had a profound effect on its viewers as well as its stars, including Kaley Cuoco, Jim Parsons, Johnny Galecki, Kunal Nayyar, Simon Helberg, Melissa Rauch, and Mayim Bialik. As a result, the CBS hit sitcom went on to run for a record-breaking 12 seasons, making it one of the longest-running comedies in television history.

There were 12 seasons of the humorous sitcom The Big Bang Theory. However, things got a little more heated behind the scenes in the 12th season, especially after Jim Parsons revealed he wouldn't be coming back.

Many members of the cast were taken aback by the decision because his co-workers weren't expecting him to make such an announcement.

In an open discussion about their feelings following Parsons' departure from The Big Bang Theory in 2018, the actors admitted that they weren't ready for the significant change. The only actor who knew about it was Simon Helberg. 

We'll look back at Jim Parsons' perspective and how the actor felt about bringing the show to an end. 

The Show’s Creators Never Thought of Continuing It Without Jim Parsons

In Jessica Radloff’s book, The Big Bang Theory: The Definitive, Inside Story of the Epic Hit Series, former cast members of the CBS sitcom, including Johnny Galecki, Kaley Cuoco, and others, discussed how they felt about the circumstance. Jim Parsons allegedly thought the show could go on without him playing Sheldon Cooper, but the producers had other ideas, according to showrunner Steven Molaro.
