On March 16 and 17, 77 percent of the live video streams of the first round of the NCAA tournament originated from work locations, ComScore Networks said.
CBS Sportsline, CBS Sports and the NCAA teamed up for the inaugural broadcast of March Madness on the Web.
The live coverage delivered 14.9 million streams during the first two days, and 16.4 million streams over the first four days, which covered two rounds of the championship.
Not everyone trying to watch on the Web got to see the live broadcasts. During the first day, 79 percent of 608,000 unique visitors accessing the feed actually viewed the game, ComScore said. On the second day, 88 percent of the 524,000 people accessing the video actually saw the games.
"The popularity of March Madness On Demand is a testament to the significant progress of streaming video over the past few years," Peter Daboll, president of ComScore, said in a statement.
