The Big Bang Theory season 10 to be last of the series?

The cast's salary alone is enough to discourage CBS to continue the series who previously stated that there will be two more season of the popular sit-com.

The popular sit-com, "The Big Bang Theory" was reported to renew with two more seasons but the continuous drop in viewership made the fans worry about the fate series. Though the numbers were good enough to be the No. 1 show of the week on broadcast television, but as compared to the previous seasons, it's low.

"The Big Bang Theory Season 10 finished first in both adults 18-49 (2.5 rating) and viewers (11.89 million) for the week of April 10. Empire, on the other hand, was a close second in the 18-49 demographic at 2.3 while Dancing With the Stars came in at No. 2 in viewers at 10.31 million," the bitbag reported.

The ratings are declining year after year. However, it still remains as one of the highest-rated TV series both on CBS as well as network television.

With its April 13 episode, "The Separation Agitation" the alarmingly low rate among adults 18-49 was noticed and critics blamed it on the lack of interesting story.

Moreover, according to the report, the rising production cost of the show is also a major concern. The Big Bang Theory is now expensive to produce. The cast's salary alone is enough to discourage CBS to continue the series who previously stated that there will be two more seasons of the popular sit-com.

The lead three stars of the show, Kaley Cuoco, Johnny Galecki, and Jim Parsons get $1 million per episode. The supporting actors Kunal Nayyar and Simon Helberg received a little less previously, but Deadline reported that all the five members of the show will have an equal pay of around $1 million per episode. Galecki , Parsons, and Cuoco demanded an equal pay during the previous installments.

Moreover, according to the new contract, Nayyar and Helberg will also have the same pay-check as their co-stars. Other actors like Mayim Bialik and Melissa Rauch will also have major pay raises.
