Facebook Launches First Agency-Designed Ad Unit With Allstate, Hallmark

For the first time, an agency-designed ad unit goes live on Facebook today. The unit -- called Comments -- is the result of an AdExpo Facebook held last year, where it gathered agencies and challenged them to create a new way for Facebook users to engage with brands. The comments from users and their friends have the ability to become a corresponding sponsored stories. Out of the 100 ideas submitted, Leo Burnett, Chicago's was selected. The move is part of Facebook's initiative to work closer with advertising agencies and creatives.
