Yahoo To Announce Large Video Acquisition—Maven Networks For $150 Million.

[Update 2/12/08: The deal has been confirmed. The price was $160 million.]

We’ve gotten word that Yahoo will make an acquisition announcement of a video startup today or tomorrow. At first we thought the target might be Metacafe, which was almost acquired by Yahoo just following the Google/YouTube deal in 2006. Shortly after, it made a small acquisition in Jumpcut, a Web-based video editor. But It’s not a video aggregator, we’ve heard, but a platform company. And the price is north of $100 million.

The price point limits the number of candidates. Brightcove is our top guess. If it is Brightcove, the price would have to be well north of $100 million, given that investors have poured $86 million into the company so far. More as this develops.

For an excellent overview of the online video space and its participants, see this post written by Brightcove CEO Jeremy Allaire and SVP Marketing Adam Berrey.

Update: It is not Brightcove. It is Maven Networks, another Boston-based video startup, three independent sources confirm. And the price is believed to be $150 million. Maven is a video-hosting platform for media sites, including Fox News, CBS Sports, CNet, and Scripps Networks. But Yahoo would probably want it more for its video-ad network, targeting, and insertion technologies. Maven has raised $30 million to date from investors include Accel, General Catalyst, and Prism Ventures.
