Imagine a 12 foot LED display on the side of a bus that could target time of day, zip-code, block, and ethnicity. Well, it’s a reality. And since Titan plans to invest $90 million into digital signage in the next six months, I would say this is a fairly good start.

The bus digital signage in this case will be rolled out to over 200 buses in New York, Manhatten, and Chicago by first quarter 2009. In this case, the great part of this story is the integration with GPS. The GPS tracking system integrated into the bus digital signage makes for a great way to specifically target the neighborhood of interest. So, for instance, coffee can be advertised in the morning and beer for after work. Kind of crazy.

The original post on this issue stated the following:

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.

So, if you’re in New York, Manhatten, and/or Chicago expect to see some dynamic bus digital signage. Be aware: you’re probably being targeted.
