[quote name=\'adamjk\' date=\'Aug 19 2004, 12:25 PM\'] I am quite confident that it will be a while before they bite the dust, but as we all know, all good shows must come to an end at some point. [/quote]
Actually, that's just not true. There are many shows (Meet the Press, Today, Entertainment Tonight, SNL) that could easily last as long as television itself, or at least until a substantial change in the economic model that makes them viable. And unlike TPIR, both Wheel and Jeopardy are driven much more by their content than by the appeal of their host, so they could easily continue long after Pat, Vanna or Alex steps down.
Time will tell whether their appeal will match those others I mentioned, but the idea that "all good shows must come to an end" is not a safe assumption.
