MySpace launches self-serve ad network for small business

MySpace today launched their self-serve ad network for small business. A lot of the blogs out there have already covered it, so I thought I would just make some quick points in summary:

• Advertisers can only choose from 2 ad sizes - 728x90 and 300x250
• They have a flash based interface where you can choose a template for your ad (Alternatively you can upload your own custom creative)
• Advertising is currently only available in the US.
• There was mention about only age, gender, and location targeting being available - but it seems like you can also target by interest category. It can get quite specific as well. After choosing books, I can choose the Titles sub-category, and then even choose specific books - only the most popular ones are there of course. (I chose the Da Vinci Code and was told there are 479,024 myspace users with this interest)
• Although you can bid on how much you pay for click, the minimum is 25 cents. Also, the minimum budget to begin a campaign is $25.
  

Overall, this system seems quite similar to facebook's self-serve advertising and it should generate some decent revenues. One of advantages that myspace has is the number of users who are music focused and will spend the money to promote their myspace page. It will be interesting to see what % of their revenues come from these users in comparison to external advertisers.
