I was wondering since The Simpsons is going over the 300 episode mark soon,what will the next show to over go over the 300 episode mark??? My guess is probably Law and Order,what would be anybody else's guess???

I would say Law and Order, NYPD Blue might get there, they have a contract til 2004 and currently it is one of ABC's best shows (which is sad) so it might get picked up for longer.

Law and Order will definitley cross it next year.

None of the current long running shows will make it, IMO.

Besides Fraiser (which won't make it if it ends next year or the year after), the closest, NYPD Blue, will need 4 more seasons after this year to do it. I don't think that will happen, but it's possible.
