PPVs go out live and can be watched on demand as soon as they finish. No delay on those. And yes, every single WWE, WCW and ECW pay per view ever, plus every Raw, every Smackdown, every WCW Monday Nitro and WCW Thunder, every ECW weekly show TV and much more, long-dead wrestling companies most people have never heard of, like AWA, Smoky Mountain Wrestling, All Star Wrestling and Global Wrestling Federation. Every program WWE have ever made is up there, should you want to watch Tuesday Night Titans or Saturday Nights Main Event from 1987. They even make their own reality shows, documentaries, even cartoons (all wrestling themed). You could be watching it for the rest of your life.
Make sure you watch the Monday Night Wars documentary series, it's excellent. It's focused on the period between 1996-2000 when Raw was at its peak and has loads of archive footage of Stone Cold, DX, McMahon, NWO, Mankind, The Rock etc, and shows all the highlights without you having to search through hours and hours of Raw episodes. Plus it's just a great story.
I love wrestling and I want WWE to be good again.
