Like most of you, I've been reading the news over the last couple of days from Unicast and Eyeblaster, about their "new" ad units. Eyeblaster has a 100K unit now, and Unicast created some buzz with their between pages unit which are really jumbo size Superstitial pop-ups. Does the Internet need bigger pop-ups or heavier banner ads? The more I read about these so-called "new" units, the more I keep thinking that this sort of sounds familiar. So, I thought I'd check on what some of the more strategic agencies and advertisers already have been doing for months.
