With all of the news about Microsoft's acquisition of aQuantive, you might be looking for some background information about the ad industry in general. Avenue A | Razorfish was at MIX07 in force, and we'll be running some more about them on this feed in the near future. But in the meantime, you should check out this discussion from MIX06, "Beyond the Banner: Advertising on the Web and Where it's Going". We had top people from aQuantive, Yahoo!, Microsoft and more giving a crash course in the ad industry. Although a lot has happened since then, the topics they discussed are still surprisingly timely (it was forward-looking, after all). If you're an RIA designer or developer, you'll find it illuminating.
