A report by Deadline has confirmed that The Big Bang Theory has been renewed through to 2019, bringing the series up to twelve seasons.
This comes on the heels of a spinoff series based on the early years of Sheldon Cooper, played in the original series by Jim Parsons. The two-season renewal comes after the show's main stars - Jim Parsons, Johnny Galecki, Kaley Cuoco, Simon Helberg and Kunal Nayyar - all signed new contracts to continue on for another two years.
Now in its tenth season, the production cost for each episode of the series is now close to hitting $10 million per episode according to Deadline's sources. That, however, pales in comparison to the money that the series has made in syndication - a little under $1 billion so far.
Most of the production costs come from the actors' salaries, with Parson, Galecki et al pulling in just under $1,000,000 per episode on the series. Meanwhile, series regulars Melissa Rauch and Mayim Bialik are expected to have their per-episode salary bumped up to $500,000 per episode once their contracts have been signed off.
