WWE has started putting their home video releases on iTunes. At this time they have Over The Limit 2010, Fatal 4 Way 2010 and Money In The Bank 2010 at $12.99 per event.
The events are also available in HD video on there at a cost of $17.99 per event. This is interesting because these PPV events were not released on Blu Ray, yet there is now another means to own them in HD quality as they were originally shot. Alternatively you can get individual matches from the shows for $1.99 each or $2.99 in HD.
Also it looks like they are selling the documentaries from Ricky Steamboat: The Life Story of the Dragon and The Rise and Fall of WCW on there too. Whilst as collectors here we appreciate the physical media of WWE DVDs in their cases for collection purposes, it definitely makes sense for the WWE to offer these services to the ever growing download market.
