Putting Tube in the picture

On Advertising: Putting Tube in the picture - Technology - International Herald Tribune: "Viacom Outdoor, a billboard operator, is preparing what it calls the biggest deployment yet of digital video technology in the service of "out of home" advertising, investing £72 million, or $136 million, over the next two and a half years to install 2,200 screens in the subway network.

London is emerging as something of a laboratory for digital experimentation in outdoor advertising. Under a recent agreement between another out-of-home specialist, JCDecaux, and BAA, which manages British airports, Decaux plans to install 1,600 digital ad screens at London Heathrow Airport and other sites. At Heathrow alone, the French company plans to invest more than £20 million in the upgrade."
