Next Up: TV Ads Just For You, Dear Voter

The days when political campaigns would try to make inroads with demographic groups such as soccer moms or white working-class voters are gone. Now, the operatives are targeting specific individuals. And, in some places, they can reach those individuals directly through their televisions.

Welcome to Addressable TV, an emerging technology that allows advertisers -- Senate hopefuls and insurance companies alike - to pay some broadcasters to pinpoint specific homes. Data geeks look at everything from voting histories to demographics, magazine subscriptions to credit scores, all in the hopes of identifying their target audience. The advertiser then hands over a list of targets and, without the viewer necessarily realizing it, the ads pop on when viewers sit down to watch a program if their broadcaster has the technology.

"This is the power of a 30-second television commercial with the precision of a piece of direct mail targeted to the individual household level," said Paul Guyardo, chief revenue officer at DirecTV. "Never before have advertisers had that level of precision when it came to a 30-second commercial." At the same time, NBC and parent company Comcast are opening the door for advertisers to target specific households using video-on-demand services in 20 million more households. The communications giant is not yet ready to implement the targeting during live broadcasts, though. And GroupM, which handles about one-third of the world's ad buys, recently formed a division to handle such addressable advertising.
