Price is obviously #1
Then Wheel, Jeopardy, Millionaire, Feud, what's #6?
Note: I said consecutive so years off wouldn't count...Sale, maybe? I could be answering my own question but I could be wrong.
If we're only counting US game shows, if I understand your criteria correctly I
think the order is like this (not 100% sure, though):
* #1 is Washington D.C.'s
It's Academic (57 seasons)
* #2 is Baltimore's
It's Academic (47 seasons)
* #3 is
Price (46 seasons)
* #4 is
Wheel (35 seasons if only nighttime is counted, 43˝ if daytime is added in as well)
* #5 is Ohio's
Academic Challenge (35 seasons)
* #6 is
Jeopardy! (34 seasons)
If you're only wanting national shows, then I think it's like this (again, not 100% sure):
* #1 is
Price* #2 is
Wheel* #3 is
Jeopardy!* #s 4-6 depend on whether you consider the ABC and syndicated versions of
Millionaire as one run. If so, it'd be
**
Millionaire (19 seasons)
**
Family Feud (19 seasons; debuted slightly later)
**
What's My Line? (17˝ seasons)
** Otherwise, it'd be
Feud-
Line-
Millionaire.
