We launched a magazine on the Howard Stern Show. Looker Magazine.
www.lookergirls.com and really didn't get much of a bump from the anouncement.
We went further then a simply plug, as we had Linsey Dawn McKenzie
www.linseysworld.com on the show, and he got to tease her about her boobs being real.
We did this a while back, when the show was over the radio, and in my opinion had allot more exposure then it does now.
All I'm saying, just don't spend to much for the plug, you may not be able to quantify or see it's value.
