Mainstream media can automatically produce podcast version of their content.

Odiogo converts dynamic web pages into high-quality audio files.
Odiogo uses sophisticated algorithms to filter-out the non-content item (links, legends, ads, etc.) of your web pages. This “cleaned” content is then processed by advanced text-to-speech technology to produce nearly human quality audio output. The files Odiogo produces can be easily uploaded into an iPod/MP3 player, listened to on a mobile phone or played on a PC or Mac.
