Ben just posted some interesting stats on our efforts with the NBC Olympics site:
During the 17 days of the games, the site had 51.9 million unique visitors (106% more than Athens and Torino combined) 1.3 billion page views 75.5 million video streams initiated (601% more than Athens and Torino combined) 9.9 million hours of video watched (equivalent of 1,126 years of video). More than 27 minutes per user average viewing time (compared to 3 minutes for sites using other streaming video technologies)
During the 17 days of the games, the site had
