Thanks to Springwise for turning us onto this one:
"London buses will soon carry the world's first GPS advertising. Yell.com has retained 25 buses outfitted with digital LED panels that will show messages matching the bus's geographical position.
Yell.com is using the GPS panel system as part of a five-month campaign to raise awareness of its local search facility. Besides intelligent buses, the campaign (developed by AKQA) also includes knowledgeable bus shelters: interactive screens on bus shelters will highlight local shops, restaurants and bars and help users find their way."

What a cool way to give consumers exactly what they need when and where they need it. A wonderful way of bringing search functionality out of the PC and into the consumer's life on the city street.
