comScore's Video Metrix service has released data concerning online video viewing for August 2009 and as it turns out, online video received its biggest audience ever! Over 161 million internet users watched online video at some point in August and the average viewer watched almost ten hours of video during the month (or an average of 157 videos). Over 25 billion videos were viewed with Google-owned sites accounting for at least ten billion of those.
Of course, one reason the top honors went to Google sites is because the company owns what is probably the most popular website for viewing online video: YouTube. 99% of Google's ten billion videos viewed were viewed at YouTube.com. Microsoft came in at a very distant second with about 547 million videos viewed, followed by Viacom with 540 million and Hulu with 489,000.
As for unique viewers, 121 million Google visitors watched an average of 83 videos during August, with Microsoft, again, coming in at second with almost 55 million viewers watching about ten videos all month, and Yahoo! coming in third with just over 51 million viewers watching just seven videos.
comScore also measured data relating to the top online video ad networks by comparing potential of unique viewers to viewer penetration. In August, Tremor media was number one, reaching 42% of the potential viewing audience with YuMe Video ranked second with about 37% and ScanScout coming in at a close third with 36%.
So what else did comScore find? Well, 81.6% of the entire United States internet audience viewed an online video in August and the duration of the average online video viewing was about four minutes. Read more at comScore, Inc
