‘Primetime’ U.S. Video Streaming Activity Occurs on Weekdays Between 5-8 P.M.

Bolstered By Youtube.Com, Google Ranks as Top U.S. Streaming Video Property in January Accord ing to Comscore Video Metrix

RESTON, VA, March 21, 2007 – Comscore, a leader in digital media measurement, today released the latest data on the U.S. streaming video market from its Video Metrix service. In January, nearly 123 million people in the U.S. (70 percent of the total U.S. Internet audience) viewed 7.2 billion videos online. The average video streamer viewed 59 streams during the course of the month – nearly two videos per day – and viewed an average of 151 minutes of video online during the month, with the average viewing time per video registering 2.6 minutes.

* Note: “Streams” (which includes both streaming and progressive download video) are attributed to the property that provides the stream, including embedded videos viewed on another site.

Google Sites was the top streaming video property in January, as measured by total unique streamers (54.7 million) and total video streams initiated (1.167 billion). The lion’s share of video streaming activity at the property occurred via YouTube.com, which accounted for 992 million video streams initiated.

Weekdays from 5-8 P.M. Deliver Highest Relative Consumption of Online Video

Comscore also conducted an analysis of U.S. video consumption by daypart, which showed that people were relatively more likely to view video on weekdays than on the weekend. In fact, peak relative viewing occurred between the hours of 5:00-8:00 P.M. on weekdays, when video consumption was 60 percent higher than average. Meanwhile, the highest relative video consumption on weekends occurred between the hours of 7:00-11:00 P.M., when streamers viewed 31 percent more video than average.

“Marketers have a great opportunity to leverage Internet video in conjunction with their traditional TV buy and essentially double their ‘primetime’ commercial airing hours," said Erin Hunter, executive vice president of Comscore. “‘Primetime’ TV viewing occurs between 8:00 and 11:00 P.M., while ‘primetime’ viewing of online video occurs during the preceding block of time – between 5:00 and 8:00 P.M. on weekdays. Shrewd marketers will utilize a multi-channel strategy to capitalize on these adjacent ‘primetime’ blocks in order to maximize their marketing impact.”

*Daypart Index = (Daypart Share of Weekly Video Consumption / Daypart Hours as a percent of Total Week) x 100
