[quote name=\'hmtriplecrown\' date=\'Sep 3 2004, 01:13 PM\'] Could Ultra Quiz be considered a tournament of sorts? If so, there were more than 128, 144, or however many people took part in The $40,000 Chain Reaction. [/quote]
Started with a boatload of players, was reduced down to one over the course of several rounds, that constitutes a tournament to me.
(Of course, by that same definition, so's an isolated episode of Weakest Link. Or even Singled Out. So clearly it's not a good definition.)
