July is named for Julius Ceaser, and like that Roman Emperor, YouTube “saw and conquered” the world of online video again a month ago. The undisputed leader of online video claimed 49% share of video viewing visits, up 1.3 percentage points versus June and 8.1 versus a year earlier.

July was also the second time that YouTube overtook MySpace in terms of US-based unique visitors at the domain level. The previous occasion was April, 2008.
Over the past two years, YouTube steadily approached MySpace, building enormous momentum from a base of 20 million UV’s. Since it caught up with MySpace in February, 2008, YouTube’s surge has leveled around 60 million UV’s.
