A source informed us a few days ago that they were still in discussions about a streaming option for Double or Nothing and B/R Live is entered into the conversation. That is the Bleacher Report streaming service. https://live.bleacherreport.com
B/R Live is owned by AT&T’s WarnerMedia which also owns TNT. TNT is expected to make the announcement this week that they will be the basic cable home of AEW TV live each week starting in the Fall 2019.
The Double or Nothing pre-show will air free and live across AEW’s YouTube, Facebook, and Twitter on 5/25/19.
