Service From Start-Up Lets Users Set Aside Web Promotions With 'Keeper' Button

Kraft Foods, Unilever and 19 other major marketers have signed up with a new effort to get users to store and revisit ads they see on the Web, rather than ignore them.

The new service -- from start-up AdKeeper -- bills its technology as "bookmarks for banner ads" or "TiVo for advertisements." Advertisers drop a small button into the corner of their ads that shows up wherever the ad appears. The button, a small k, expands when users mouse over it, telling them to "keep this ad." Users can click on it to save the ad to a separate webpage and continue browsing. Later, they can return to that ad-collection page and scroll through, filter and click on the ads.
