RESTON, VA, October 19, 2006 - comScore Media Metrix, a leader in digital media measurement, today released its August rankings of the top U.S. streaming video properties.  Fox Interactive, which includes MySpace.com, led the way with 1.4 billion streams during the month, or 20.1 percent of the market.  Yahoo! Sites ranked second in video streams initiated with 823 million (11.8 percent share), followed by YouTube.com with 688 million (9.9 percent share).

"comScore Video Metrix offers industry experts the information they need for understanding the growing Internet video landscape," commented Erin Hunter, executive vice president of comScore's Media and Entertainment Group.  "Historically, traffic metrics were the only tools available for analyzing this space.  While these measures provide important information on the number of unique visitors to a site, they do not properly measure how many people are actually viewing video content across the Web and how many streams they are viewing, both of which are vital to understanding video's advertising capacity.  Our data illustrate that the top-ranked sites by streaming activity do not directly correspond to the most trafficked sites, rebutting the sole use of traffic as a gauge of video consumption."

* As of August 2006 data, MySpace.com is being included as part of the Fox Interactive property

** Note: Streams are attributed to the property that provides the stream.  For example, the

YouTube data include streams that occurred on their Web property and on other properties

whereby YouTube provided those streams.

• In August, 6.98 billion video streams were initiated by U.S. Internet users.
• The average U.S. streamer consumed 63.3 streams during August, or approximately 2 streams per day.
• Streamers at Fox Interactive showed the highest levels of video consumption per person at 35.5 streams per streamer, followed by Yahoo! Sites (20.6 streams per streamer) and YouTube (19.4 streams per streamer).

• The U.S streaming audience increased 4 percent from July to reach 110.3 million streamers in August, representing about 64 percent of the total U.S. Internet audience.
• Yahoo! Sites attracted the most streamers in August with 39.9 million, followed by Fox Interactive (39.5 million) and YouTube (35.5 million).
