January 2009 data from the comScore Video Metrix service shows that US internet users viewed 14.8 billion online videos during the month, representing an increase of 4% versus December 2008.
In January, Google Sites once again ranked as the top US video property with 6.4 billion videos viewed (43% online video market share), with YouTube.com accounting for more than 99% of all videos viewed at the property.
Fox Interactive Media ranked second with 552 million videos (3.7%), followed by Yahoo! Sites with 374 million (2.5%) and Viacom Digital with 288 million (1.9%). Megavideo climbed 15 percent (103 million videos) in January to capture a spot in the top ten for the first time.
comScore also found that 76.8% of the total US internet audience viewed online video in January.

In other research, comScore forecast that the coming year will see a rise in online video viewing and a shift to online ad spending (see Online video viewing to rise in 2009).
Viewing of TV and movie content online continues to become a more mainstream behaviour, said comScore, offering advertisers a new opportunity to capitalise on this highly engaged audience.
Leichtman Research Group recently revealed that 34% of US adults online at home report that they view some type of video online at least weekly, including 11% who view video online daily (see US online video viewing increases).
