In the mid-2000’s WWE released a few of their documentaries on the failed Universal Media Disc (UMD) format for the PSP (Playstaiton Portable).
You didn’t get any of the bonus matches that were on the DVD versions- you just got the documentary part, which kind of sucked.
Plus you had to watch it on a tiny screen.
People didn’t want to watch movies on their PSPs. They wanted to buy DVDs and watch them on their TVs.
So the format died a pretty quick death, and anyone who bought one of these WWE documentaries on UMD disc figured out what a steaming pile of WrestleCrap they really were!
