#2 Will Win: WWE is entrenched in the entertainment industry in a way AEW is not
From the days of WWE's classic era, Vince McMahon has pushed strongly for a foothold in mainstream entertainment media. In the 1980s, he did this by creating the "Rock and Wrestling Connection." In the 1990s, he did this in part by having his wrestlers such as Bret Hart appear on cutting edge shows of the era such as the Simpsons.
And in the 2000s, it was the burgeoning fame and movie stardom of The Rock and his Saturday Night Live appearances which kept WWE in the constant media limelight.
In short, WWE has entrenched itself into the media empire in a way that AEW simply has not done. In reality, it would take All Elite Wrestling decades to build such relationships with Hollywood, which means WWE has a huge head start.
