Comscore Data Confirms Reports of 100 Million Worldwide Daily Video Streams from YouTube.com in July 2006

More than 63 Million People Globally Visited the Site During Same Month

RESTON, VA, October 11, 2006 – Comscore MMX, a leader in digital media measurement, today announced the results of an analysis of worldwide video streaming activity from YouTube.com, confirming that an average of 100 million video streams were served per day in July 2006.

In July, more than 63 million people (Age 15+) worldwide visited YouTube.com, 16 million of whom came from the U.S. On a daily basis, the site attracted an average of 6.2 million visitors worldwide, with 1.6 million residing in the U.S. The site also ranked as the 17th most visited property worldwide during the month.

*Worldwide MMX data is reported on Persons Age 15+
**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.

While visitation is one metric for measuring a site’s popularity, Comscore’s Video Metrix service possesses the unique capability of measuring actual streaming activity. In July 2006, YouTube served nearly 3 billion video streams worldwide, with slightly less than one-quarter of the total activity streamed to U.S. locations. On an average daily basis for the month, 96 million streams were served worldwide, and 21 million in the U.S.

“Several media outlets have reported that YouTube streamed 100 million videos daily in July, and the results of our recent study corroborate this report,” said Gian Fulgoni, Chairman of Comscore Networks. “In fact, our daily streaming data show that YouTube.com first surpassed the 100 million threshold on July 17th, which coincides with YouTube’s own announcement that they had reached this impressive mark. Our streaming data covering more recent months will be published shortly, and will show that YouTube’s streaming total now far surpasses 100 million per day.”
