Obviously you’re going to say adsense, but seeing that you have to be 18 (and they verify with your SSN) so that’s not going to happen.
What do sites like Myspace/Facebook use, when they display flash ads? How does BA shoe graphical ads through adsense? I really want to display catchy flash/graphical ads, what provider should I go through? (I’d prefer if I got payment through paypal, if not, whatever)
