#3 All of the announced AEW live events are in big venues
While Double Or Nothing is considered to be All Elite Wrestling's debut event, the roots of AEW go back to last year's All In at the Sears Centre Arena in Illinois. Those two shows were both arena events which sold all publicly-available tickets in much less than one hour.
The third official AEW event is Fight For The Fallen at Daily’s Place Amphitheater at TIAA Bank Field on July 13th. The next event announced for Fight For The Fallen is All Out, which is scheduled for August 31st at the earlier-mentioned Sears Centre. In turn, of the first four announced AEW live events, you have four massive live events.
Looking back into history, wrestling companies had to work their way up into arenas. Furthermore, WWF had some time in both the 1980s and 1990s where some of its live events took place in high school gyms. ECW has been mocked for playing "bingo halls," WCW at one point in the 1990s had to cut down on its house shows for financial reasons, and TNA at a certain point altogether halted its house shows.
So currently AEW is batting 1.000 — to use a baseball term — when it comes to booking high-profile, major shows which people are coming to see. It will be interesting to see what changes are made, if any, once AEW begins its weekly television show.
