Here's a fun little list of the top video sites based on their usage on MySpace. With YouTube taking the title by a mile, it's no wonder News Corp is considering blocking the service.
1) YouTube
2) MySpace Video
3) VideoCodeZone
4) Video.Google
5) Bolt
6) SingingFool
7) MetaCafe
8) Grouper
9) Break
10)Video.Yahoo

Isn't it funny that Google and Yahoo, two of the biggest internet companies of the past 10 years, have struggled so much to make inroads in the internet video market. Obviously that will change now that Google owns YouTube.
