LinkedIn Releases API, Opens Floodgates | Adweek

linkedin continues to move aggressively to increase its allure for advertisers. this excerpt describes why an API is so important for big advertisers:
An ads API is like steroids for an ad platform. Consider Facebook. The social network in 2009 began letting a few companies access its ads API and brought even more on board in 2010, when advertising revenue grew 145 percent to $1.87 billion. The following year Facebook officially released the ads API, which would open it up to more developers who would be able to manage and run more ads for marketers. Facebook closed 2011 with $3.15 billion in ad revenue; it already has $2.95 billion in ad revenue over the first three quarters of 2012. Obviously the ads API isn’t the only reason Facebook has seen such a steep rise in ad revenue—hitting a billion users and increasing ad rates certainly helped—but the API definitely catalyzed that growth.
