I frequent the site Hulu often when I have missed a show, or wanted to show someone something funny I watched. The site has just reached the year mark and is implementing new features to keep users on the site and bring their friends as well.

Online video site Hulu is celebrating its first birthday by adding social networking to the site. Dubbed “Hulu Friends,” users can do the usual: share videos, comment on shows and content, and view rankings. Hulu integrates with Gmail, Yahoo Mail, Hotmail, Facebook, and Myspace to help users find their friends and/or invite them to Hulu.

Hulu is experiencing 24 million visitors a month. It has risen quickly in its niche and trails only YouTube in the online video space. They began with 50 content partners and now boast over 130. They’ve grown from 30 advertisers to 175+.

Over 3.9 million Hulu players have been embedded on more than 100,000 sites.

Congrats on all the success, Hulu!
