What people miss often is that ECW had a forerunner in Philly, Tri-State Wrestling. That promotion ran in the early 90s and featured Eddie Gilbert, Cactus Jack and Terry Funk, among others. They frequently held barbed wire matches, and in addition had such brainstorms as the fan participation lumberjack match, the reverse cage battle royal, and the last blood battle royal. It's the promotion that featured Gilbert and Foley's best of 3 falls match, where each fall was a different gimmick (as an aside, this had fun results, the second fall was a stretcher match, where a wrestler had to beat his opponent so badly that he could return for the third fall, and the final cage match ended in a double DQ). They also featured matches such as Owen Hart vs. Takayuki Iizuka. ECW was very much simply a continuation of that promotion.
