With the Beijing Olympics fast approaching, NBC Universal announced it would provide 2200 hours of live competition coverage across 25 sports on NBCOlympics.com. Others will appear on-demand.

NBCOlympics.com will also include home video-style content and blogs from Olympians, part of its "Olympic Insider" feature. Widgets will be available for fans that want to host Olympic content on their own sites.

NBCU added that the Beijing Olympics would be the most comprehensively-covered event on a mobile platform. NBC Olympics Mobile will feature news and video coverage, as well as text and video alerts.

Finally, the company brokered an exclusive partnership with Microsoft. The latter's Silverlight 2 technology will host video on NBCOlympics.com both online and on-demand. And MSN will syndicate content from NBCOlympics.com, including mobile, gaming and video on-demand capabilities.

Eight days ago NBCU's TV networks reported they were 90 percent sold out of Olympics ad inventory, totaling $900 million in ad time. Days later, Senator Barack Obama's Presidential campaign announced a $5 million ad buy.

$1 billion spent on ad inventory for the Beijing Olympics will break the sales record for Olympic telecasts, reports AdWeek.
