Mappam - location-based advertising for Google Maps, Yahoo! Maps, and virtual Earth

First we delivered details about Lat49 and their solution for serving contextual ads to Google maps, Yahoo! maps, and virtual Earth. Now there's another player entering this space... from the developer; With Mappam advertisers can within minutes create campaigns on www.mappam.com targeted to geographic locales, paying only when users click through to the advertising website. Adverts are displayed to visitors on the maps of Mappam network partner websites as 16x16 pixel icons which when clicked on open a descriptive text and a link to the advertising website.
