WWE had to move to the Performance Center when the COVID-19 pandemic took away any chance of having live fans at events. They knew this wasn’t a long-term solution.
There were cries to fix WWE’s location situation ever since they settled in according to the Wrestling Observer Newsletter. They apparently started those pandemic zero fans shows with the “Feeling that they had to get out of the Performance Center.”
It was noted that AEW’s use of Daily’s Place and that larger venue certainly played into the company’s decision as well.
As far as what happened, there were minor changes following the lead of AEW, which the company hated to do but realized it had to, the changing of the hard camera and putting wrestlers as audience members.
Producing pro wrestling content in front of zero fans in a warehouse is a good idea for a gimmick match, but it doesn’t hold up for weekly programming. Now WWE is entering the ThunderDome in the Amway Center. This is apparently a much more agreeable arrangement for the company.
