no they didnt butSyndication . As it happens , seven seasons is the sweet spot for running reruns of a show on daytime TV . That allows them to show a different episode MondayFriday for long enough that when they restart , it won ' t seem too repetitive . The suits in charge of paying the production costs will therefore push for seven seasons , and usually they have the clout to get it , even if the writersactorsshowrunner feel the show can only support six seasons properly , or that the show needs an eighth season . From a monetary perspective , the amount of profit per dollar spent goes down in seasons eight and beyond , and hasn ' t yet reached maximum potential until after season six . Also , the standard contract for headlining TV actors is for seven years with some options of renegotiation during , options for dropping out , being written out , allowance to take on other roles , etc . After the contract is up , and the TV show is still popularmakes money , the actors pretty much make the show what it is in the eyes of the majority of the public , at least , so they have an upper hand in asking for much bigger salaries . It also happens that after those 7 years , the contracts are renegotiated every year or every two years , and their salaries go through the roof recent example Big Bang Theory main actors . During the first 7 years though , and you might have noticed that on many shows , actors get the executive producer credits , even if they are not directly or even indirectly involved in the decision making or creative process of making the show . This is one of the ways to bump their salary or provide honorary title , which gives them more bargaining clout in the long run .
