Yahoo is promoting the launch of its redesigned homepage with a "Yahoo has changed" campaign - created by Yahoo roster shops SoHo Square and OgilvyOne - that's centered on user-generated video, reports AdWeek. Yahoo is providing creative assets, including sample scripts, and the Yahoo yodel and logo. A microsite now features 11 videos by film school students; user-created videos will also be added.

The student videos are idiosyncratic 15-second clips that exalt the "new" Yahoo. Yahoo will promote the site across its network and run ads on sites such as TheOnion.com, MTV.com and iFilm.

"What we're allowing people to express is their creativity and passion on the network," Allen Olivio, Yahoo's vice-president of global brand marketing, is quoted as saying.
