Teen girls intrigued by CondeNet’s Flip will find they have more control over advertising than on most ad-supported sites. MediaWeek reports that the publisher and its advertisers are on the same page with the notion. The site, slated to go live officially Feb. 6, has five premiere sponsors including PacSun, Nordstrom, J&J’s Clean & Clear and Vera Wang, but no one’s saying how much ad revenue that represents. MediaWeek says sources put the packages between $300,000 and $500,000 so it could have $2 million committed already. The intriguing aspect here is the control users will have over the ads and the form some ads will take. Girls will be able to decide which brands they see for the traditional ads. There’s also a kind of DIY product placement fitting in with the notion of “Flip books”; as the users create their books they’ll have access to items like Nordstrom-supplied images of models that aren’t visibly from the store unless clicked. Clean & Clear will provide logo-and-product-less word icons.  Users will be able to write what they think about the products in their books. That user control and influence makes it attractive, an OMD strategist tells MediaWeek. It will be interesting to see how it all actually plays out.
