The Big Bang Theory, the mega-hit sitcom was just renewed for three more season, but showrunner Steve Molaro is already assuming the 10th season will be the series’ last especially given that stars Jim Parsons, Kaley Cuoco-Sweeting, and Johnny Galecki’s contracts expire! Steve said, “I’m going to move forward along with [co-creator] Chuck [Lorre] that 10 is the end unless we’re told otherwise. These are decisions that are so far away I can’t really even think about that. I have no choice but to move forward,it’s so far away.The mindset is it’s going to be the 10 and then we’ll see what happens after that.”
