Skype's streaming-media offspring Joost.com (still in Beta I might add) signed its first big deal with the main stream media yesterday:

CBS is the first national broadcaster to ink a deal with Joost, but it isn't an exclusive deal. CBS will be distributing content on a number of web portals as well, including AOL and MSN. The company also hopes to strike a deal deal with the new News Corp/NBC joint venture. As you would expect, CBS will be licensing shows that have already aired on television. Early titles will include the original CSI, NCIS, and the CBS Evening News with Katie Couric.

The deal charges Joost 90% of any ad revenue generated by the service.
