The 360 reports on a proposal to form essentially a commodities style market for advertising in the United States:
A consortium of some of the biggest advertisers in the United States has plans to move the ad industry out the era of the cattle exchange and into the internet age. They’re looking for someone to build an ADSDAQ – an online exchange similar to the NASDAQ where advertisers and media owners can trade.
Interesting idea. I wonder if blogs could play a role?
