On the theme of whom to believe when it comes to traffic, Bambi Francisco of Market Watch wrote a piece that argues (using comScore data) that MySpace is the biggest video site in the US based on video streams and unique users.
YouTube by that analysis turns out to be third; Yahoo! Video is second.
But recent (August) Hitwise data reflects the following in terms of rankings (based on share of visits):
- YouTube: 45.46%
- MySpace Videos: 22.99%
- Google Video: 10.25%
- Yahoo! Video: 6.06%
- MSN Video: 5.92%
