This deal is huge for TNA, as it gets them back into the realm of 'basic cable' for the first time in a long while, but it's terrible for AMC as it completes their scope-creep into essentially being a clone of TNT or USA Network.
Speaking of, the potential Netflix/WB deal could stir the pot some where the rasslin' landscape is concerned - Netflix is tied up with WWE, but their biggest competitor, AEW, is heavily embedded with the Turner networks and HBOMax. I know the cable channels aren't part of Netflix's offer, but it'll be interesting to see how this all shakes out - assuming Netflix consolidates HBOMax into their existing footprint, AEW will likely need to find a new streamer - possibly Prime Video, as I think they're one of the few major streamers that aren't somehow tied up with WWE.
