Suddenly, everybody can (and, really, must) advertise on TV, because it'll be so specific...and so dynamic. If you start shopping for a new WiFi access point in the morning, Google will know, and that night when you watch Two and a Half Men, your ads will be from D-Link, Linksys and Belkin. And, further, they'll know that an intelligent buyer lives at your IP, so your ads won't show you a hot model demonstrating how they're plug-and-play, but will instead feature a quick recommendation from the SveaSoft guy about which AP's the best one for hotrodding.
This can be taken two ways: one is technical, one is quite funny.
