That's true, but it seems strange that every PPV from all of the big companies going all the way back into the '80s was already waiting for us, but we're lucky to get a 1994 Raw some days. They're also pretty good at getting the latest Raws up when the waiting period is over, which makes it even weirder.
I wonder if it's a digital restoration process then, PPVs first and then TV shows. I wonder if there are licensing issues they need to clear up on certain TV Broadcasts too. I don't know!
There is at least a digitization process as everything through a certain point (I have no idea when they went digital, HD transition maybe) was done on film or tapes. It would make sense that they digitized the PVPs first since they have been making DVDs for a while and have pulled from the PPVs primarily.
