I am interested in placing ads that are specific to the content on my site. I am using Google AdSense now and for the most part that does cater to the content but not enough for me. For instance I am doing a review of Treo Windows Mobile Cellphones and I want to insert a Verizon Wirless or Sprint EVDO(mobile broadband) banner ad into the story as I detail in my content the benefits of having such a phone and subscribing to a mobile broadband plan. Can this be done with Google AdSense...DoubleClick...some other way? Cheers, Chaser
