Some Shows don’t know when to end

Last month, Larry King Live ended after 25 years. Oprah’s show is also ending after 25 years. Sunday, Hannah Montana ended after 5 years. And two days ago, Regis Philbin announced that he will be leaving his talk show.
However, some shows just don’t know when to end. Like American Idol. After 10 seasons, plenty of rule changes, and new judges, this show just won’t stop. But why?
Other than the obvious reason, money, it’s puzzling why the show’s still on. The past few winners haven’t been that famous or successful, and at this point, the real winners are the runner-ups and other contestants who aren’t contractually obliged to 19 Entertainment.
With both Paula Abdul and Simon Cowell gone from the judging table this year, the show won’t be the same. While the contestants’ talents always varied, the judges’ antics would always be there. But now that the two interesting judges are out of the picture, why will people watch?
As rude as this sounds, I personally want to see the show end already. I mean, with Simon bringing The X Factor and Paula Abdul with that one new dance show (Live to Dance?), the more memorable judges have new shows, so people could just watch those. And I’m pretty sure the new ‘It Reality Show’ is Dancing with the Stars. So can’t it just end already? Ten seasons is a good run, right?
