The Direct Market Exchange (DMX) will stop serving ads Jan. 31 2010, although users will be able to access reports until March 1. http://www.mediapost.com/publications/?fa=Articles.showArticle&art_aid=118327 I think it will affect small networks that has no advertisers of their own
i think the abd ones like mediashakers and such will close but the strong one like cpx ineteractive who has probably it own database of advertisers will probably do allright but be prepared for your rates to drop just what i thinking
Yield manager is Yield manager. Direct Media Exchange is just a platform thats get its ad feeds from those Yield manager network. I already start to setup my new ad code which consist of several links i been using at DMX through my OPENX server.
