This past Saturday's AEW All In: Texas pay-per-view (PPV) had an extraordinarily long runtime of six hours, excluding the Zero Hour pre-show. As a result, it became the longest wrestling PPV in history, surpassing WrestleMania 35's runtime of five hours and twenty minutes.
Dave Meltzer discussed this in the latest episode of Wrestling Observer Radio, explaining that AEW aimed for their show to coincide with WWE's Saturday Night's Main Event. Meltzer also mentioned that the event would have likely concluded earlier if not for the ongoing "wrestling war." WWE had previously scheduled NXT Great American Bash and Saturday Night's Main Event for July 12th, the same day as All In, and hosted Evolution the following night.
According to the report, AEW made a conscious decision not to be “bullied” by WWE’s recent counter-programming efforts and chose to go head-to-head with the NBC show. The company intended for their main event to be in progress when Saturday Night’s Main Event started, which indeed happened.
