SACRAMENTO, California -- As part of a $20 million investment, Alaris Media Network, a Sacramento-based company, has erected 10 billboards that can display both video and text and can be programmed with changing messages and images. In addition, the billboards include fledgling technology that is designed to identify the radio frequencies of passers-by.
If you knew the radio listening patterns, you could deduce the income, sex, race and buying habit data of the listeners. Then you could batch out appropriate content to the viewers. Alaris is not targeting individuals, but drivers en masse. For instance, if a preponderance of rush-hour drivers are tuned to a radio station known to have affluent or educated listeners, then the advertisements at that time would be aimed at them.
