Dapper a free, web-based service that allows you to create a "feed" (Dapp) for any site that you can use: as an RSS feed, a widget, in Facebook applications, and embedd into your website or blog, is applying its technology to generate contextual, display ads from the constantly changing content on an advertiser’s own site with the introduction of “MashupAds”.
MashupAds can be created in minutes using the same feed creation platform Dapper users use every day. Then, the dynamic ad wireframe can be edited and designed in Flash studio through our MashupAds Flash Toolbar. The following video shows you just how, in about 5 minutes.
