Advertising revenue from MySpace could finally start to rise substantially - two years after the social-networking site was bought by News Corp., writes BusinessWeek.

In 2006 MySpace accounted for just $90 million in ad sales for Fox Interactive. This year, though, an analyst at Merrill Lynch says that could skyrocket to $271 million. A good portion come from more content deals as opposed to traditional ads.

To achieve that sort of growth, MySpace will have to overcome various hurdles, including low ad prices. Another potential problem is that though pageviews are up overall user adoption is slowing and a bigger percentage of users are older than the demographic that advertisers might be going after.

Those last two points could hinder one potential strategy for ad sales growth: enlisting members in viral campaigns and getting them to interact with advertiser's own profile pages.
