The Brock Lesnar / Samoa Joe brawl that opened Raw is currently almost at 5 million views on WWE’s YouTube channel, far more than any of their recent videos. Almost all other videos from Monday’s Raw are under 500k views.
That seems to be a sign that people are interested in the Lesnar / Samoa Joe feud, which has actually been handled pretty well so far. Though WWE’s TV ratings seem to be in a freefall, they are still doing well on YouTube and really probably are “cannibalizing” some of their TV viewers since all the “important” parts of Raw are posted on YouTube and lots of people would probably just watch highlights that way instead of sitting through 3 hours of Raw.
