Season 8

The eighth season of The Big Bang Theory was confirmed on March 12, 2014, after a 3-season deal with CBS which renewed the series through its tenth season, meaning that it would run until at least 2017. The Big Bang Theory started on Mondays, in front of The Millers until October 20, due to the NFL's Thursday Night Football. It moved back to Thursdays on October 30, 2014 before Mom. The season premiere aired on September 22, 2014. The main focus of the season is on Penny's new career and the death of Howard's mother, Debbie Wolowitz.
On August 4, Johnny Galecki, Jim Parsons and Kaley Cuoco each signed a three-year contract for one million dollars for each episode. Simon Helberg and Kunal Nayyar have also signed contracts for three seasons for more than $750,000 per episode. There were some contract issues between Galecki, Cuoco, and Parsons; however, these issues have been resolved.
On November 11, 2014, Carol Ann Susi, the actress who played the role of Mrs. Wolowitz, Howard’s mother, died after a brief battle with an aggressive form of cancer. In January 2015, it was announced that the character of Debbie Wolowitz would pass away in "The Comic Book Store Regeneration".
