Facebook announced today on its developer blog that it will begin running ads in third-party mobile apps, laying the foundation for what will likely become the site’s mobile ad network.
From the announcement:
We are running a small test to explore showing Facebook ads in third-party mobile apps. In this test, we’ll be extending Facebook’s rich targeting to improve the relevancy of the ads people see, provide even greater reach for Facebook advertisers, and help developers better monetize their apps.
Facebook says it’s working “directly” with a small number of advertisers and publishers, and is limiting this test run to a only a few partners.
While Facebook is not accepting any additional participants in its mobile ad program right now, the site has provided a sign-up form for anyone who wants updates on the program.
