I also wonder if these really targeted ads are cost effective. If ads were run as they used to be positioned in Newspapers and Magazines, a simple area of the screen that was set aside for an advertiser, with no targeting, no tracking, and performance measured simply by "impressions" and "clickthroughs" would they work at all? It would be much better for the users. (I'm always amazed at how unusable the websites of my local TV stations are with the adblocker off. Popups and blinking things everywhere, and the page just keeps changing out from under me.)
