Might Happen: An AEW streaming service
Given the lack of interest from major networks and even cable stations toward pro wrestling promotions (look at how much trouble the venerable Impact has had in securing and maintaining a relationship with a network), it's no secret that if AEW wants to survive and thrive, they will have to find an alternative means of getting their product in front of viewers' eyeballs.
Ring of Honor has a weekly, hour long show that airs on Sinclair broadcasting partners, but the main way in which ROH fans enjoy their product is by tuning in to the ROHwrestling.com's streaming service, particularly by joining Honor Club. This allows ROH to get their content out into the market without a major network deal.
AEW might have to take a similar tactic, even if they are able to get their programming on traditional media outlets. Modern fans expect to be able to enjoy content at the click of a button, and they would be well served to examine this possibility.
