All I know is WWE killed their PPV business and TV is all that's keeping them afloat right now, so 3 hour Raw's are going to be around for a long time to come, especially since they're bleeding viewers left and right and losing the extra hour along with the ratings is an even worse idea.
I mean, looking back at Nitro, when Russo took over that show he took away the extra hour. That was a smart choice in so far that 3 hour wrestling shows fucking suck and you should NEVER do them. Problem is, normally the ratings for Nitro should have gone up about .5 of a Nielsen point just by taking away the extra hour, but they didn't, the ratings stayed about the same as the 3-hour show (meaning the show actually got less viewers), so not only did they lose money from advertising, they also lost money from dropping viewers.
WWE right now simply can't afford to lose anything, the stockholders are pissed off enough as it is, if their TV revenue drops as well, ugh.
So here we are, 3 hour Raw's that nobody actually enjoys watching and judging by the internets response, even from the marks...
...Ratings will continue to drop in 2015, even though I'm sure they will go up for a few months. Unless they drastically change the way they book the show, I think December 2015 will have even worse ratings than this year.
