New smart billboards sniff your radio-preferences from leakage from your car and tailor themselves to your taste. The next generation will network with one another to chase you from one segment of the road to another.
The billboards — in Palo Alto, Daly City and Fremont — will pick up which radio stations are being played and then instantly access a vast databank of information about the people who typically listen to those stations. The electronic ads will then change to fit listener profiles…
For example, if the freeway were packed with country music listeners, the billboards might make a pitch for casinos. If National Public Radio were on, the billboards could change to ads for a high-quality car or a gourmet grocery.
