comScore released its December 2007 data from the comScore Video Metrix service, which reaches beyond simple site visitation to measure actual online video viewing behavior. The December 2007 report revealed that U.S. Internet users watched more than 10 billion videos online during the month, representing the single heaviest month for online video consumption since comScore initiated its tracking service. Top-ranked video property Google Sites saw substantial growth and extended its video market share gains, now accounting for nearly one out of every three videos viewed online.
Google sites once again ranked as the top U.S. video property in December with 3.3 billion videos viewed (32.6 percent share of videos), gaining 1.3 share points versus the previous month. YouTube.com accounted for more than 97 percent of all videos viewed at the property. Fox Interactive Media ranked second with 358 million (3.5 percent), followed by Yahoo! Sites with 340 million (3.4 percent) and Viacom Digital with 238 million (2.3 percent).
