Thumbplay has signed another high-profile distribution deal, hooking up to put content on MSN Mobile — which made an announcement today about the content, tickets and advertising. At CTIA a couple of months ago Thumbplay announced a similar deal with AOL…the company is rumored to be shopping around for buyers for itself, and these two deals should definitely help. The deal with MSN Mobile includes more than 50,000 pieces of mobile entertainment content including ringtones, wallpapers, games, videos, voice tones and text-based services which can be bought and downloaded. The top 5 US carriers are supported. This is described as an exclusive alliance, which I can only assume to mean that Thumbplay will have MSN Mobile customers to itself (since it has a deal with AOL). How long that exclusivity will last isn’t clear, but it could be because MSN doesn’t want to get bogged down in the minutiae of provisioning content.
