How is it actually fucking with AEW though? Is anyone who is inclined to watch AEW suddenly going to go "Hmm, I think I'll watch When Worlds Collide" instead?
Even if they did, they could still watch AEW afterwards, which will still count towards AEW's streaming numbers.
I keep hearing "It's fucking with AEW" but nobody has yet to explain how it specifically does. I'm sure WWE thinks it does - but it doesn't. However, it's easy clicks and likes for pro wrestling sites to say it does. Plus, it's great fodder for the babyface (Tony Khan) to say how the big nasty heel (WWE) is continually fucking with them. It's all classic pro wrestling.
Now, running a live show in the same city is unquestionably done to fuck with AEW - you are asking the local audience to choose which they go to and potentially diminish the live gate of AEW. That is a long established shitty wrestling practice that even independent promotions are guilty of.
Broadcast shows, especially these days, are different. There is no "splitting the audience". Consumers choose how and when they watch. If I watch Dynamite live, and then When Worlds Collide, I am still watching both shows. It makes not one bit of difference that I don't watch one or the other at the exact time it is broadcast. Plus, as I said, we are now in a position where, if it really mattered that much, I actually could watch both live.
