Hulu is doing a huge promotion currently offering several websites 2500 beta invites each and lots are still available. I found three website promotions with roughly 4000 invites left for Hulu, make sure you head right out and sign up using any of the following links:
Mashable have roughly 1100 left,
Download Squad are still good with 2300 left for the taking and
Techcrunch has another 1100 left. There are probably more sites out there that received those 2500 invites and as you can from the links the url is always
http://www.hulu.com/beta/ followed by the site name without spaces.
I just visited Technorati and discovered several other blogs that received invites as well. Those are
Webware with 2200 left,
Read Write Web with 1300 left and
Gigaom with 500 left.
Everyone can signup but only users from the United States can view Hulu without problems.
