CNN reports that ComScore’s recently released July information indicates that YouTube is only the 3rd most popular video site, behind Yahoo Video and MySpace Video - conflicting with recent reports that YouTube’s share of global internet traffic recently surpassed MySpace. So who’s right? Well, both. In a sense. The ComScore report only looks at the US traffic, while the Alexa data used to support the Gaurdian article from a few weeks ago uses global data. In either position, Youtube has grown massively over the last few months - and the wealth of traffic to the leading video sites shows that online video is penetrating further and further into the mainstream.
