Nope. Number of seasons is determined by the suits. Friends is in season 10, NYPD Blue is in 11 and will end after 12. ER is in 11. Simpsons in 14. Will and Grace in 5, I believe. It varies. Most shows would consider themselves blessed to make it to 7. I'd venture an estimation that only 10-15% of shows on TV make it to 7 seasons or more. If that.
