I was reading a press release from Todd Cochran CEO of RawVoice (the people behind the blubrry network). Here is a summary:
The media-on-demand (MOD/VOD) service will allow content creators, independent film artists, bands, educators and all others who create content to sell their premium content online and through over-the-top (OTT) television. This will give consumers a centralized location to find premium content that is not available through traditional video-on-demand channels. RawVoice MyCast® system will allow consumers to organize and play back on demand all of their purchased media on almost any device at any time.
This service will be introduced through a new channel on the Roku initially, and on its own media portal. Clients will be able to sell their media on a subscription or single play basis. With Roku integration, single click purchases of media will offer the same convenience of standard video on demand service that consumers are accustomed to.
