A handful of New York City buses sport digital ads that can be programmed to target different neighborhoods, among other criteria, reports MediaBuyerPlanner.

CBS says the ads resemble TV commercials and can, for example, advertise coffee in the morning and beer after work.

The digital bus ads are 12-foot displays that use LED and GPS technology. They enable advertisers to target mass audiences by time of day, block, zip code, demography and ethnicity. Trials are underway in Chicago as well as New York.

Manhattan plans to roll out the system on 200 buses in the first quarter of next year.

Titan Worldwide, which produced the technology, has a 10-year, $800 million contract to sell ad space on the city's bus and commuter-train systems. Its digital signage — also available on rail and subway vehicles — will appear in key US markets and London, with Ireland and Canada soon to follow, according to the company.

Titan plans to invest $90 million in digital signage over the next 36 months.
