I think it's all in show ratings. If show ratings is good, it will continue as long as people is watching show. But if ratings start go badly, show get cancelled or ends.

Also it all in contract, how many seasons lead actors are signed. If they signed for 5 seasons, show will end after fifth season or continues, unless one of actors decide to leave show.
