@ Navyfrank, it doesn't matter which advertising you use, the problems with trademarked words/names arise with things like this. Say I owned the domain, ford.co.uk, which is a trademark name like XP, I make a site and put something on there serving ads like Adsense or whatever, and some of those ads are advertising Volvo's, Mercedes or any other car makes, Ford will now have good reason to DRS me for an abusive registration due to their trademarked name being used to serve up ads for their direct competitors.
