ECW embodied the Philadelphia spirit. Much like Rocky it was an underdog company but went further than anyone expected. WWF was revitalize due to “borrowing” ECW storylines & thus the Attitude era was born. WCW also befitted buying most ECW’s talent such as Chris Benoit, Eddy Guerrero & Chris Jericho.
ECW die not because it was a bad product but due to poor financial planning. In other words they grew to fast for themselves.
ECW will go down as one of the greatest wrestling promotions in history.
