Fans really don't have to panic about Big Bang Theory ratings either. CBS recently renewed the show for two more seasons, meaning that we'll be watching the shenanigans of Sheldon, Leonard, and Co. through at least Seasons 11 and 12. There were some doubts about the future of the series for a while, for reasons ranging from syndication costs to cast salary negotiations. It clearly was a complicated process to iron out the deals for the two upcoming seasons, but given that The Big Bang Theory has been TV's #1 comedy for the past five years in key demographics, it's easy to see why CBS was willing to put in the work.
