Unicast Becomes Latest MSN Rich Media Vendor

NEW YORK — MSN has added Unicast to its list of third-party rich media vendors. The New York-based online ad company joins two other rich media developers, Eyeblaster and Point-Roll, that helped launch MSN’s dynamic advertising program in September.

Advertisers and ad agencies can now place any of Unicast’s rich media formats on the Microsoft Corp. Web portal, which currently claims more than 9 million subscribers and 300 million unique users per month. Those formats include In-Between-Page ads (Superstitial transitional ads), Over-Page units (floating ads) and In-Page units (banners, skyscrapers and IMU units). General Motors, American Express and Wells Fargo are the initial marketers using Unicast ads on MSN.

The alliance with Unicast coincides with the rollout of rich media services in MSN’s 34 international markets. MSN said it uses technology to help prevent overexposure to an advertiser’s brand and multiple rich media ads from appearing simultaneously.
