Director of London David Lambert said: "The other media channels – TV, press, radio – are all facing issues. We have the best product in town."
The new division will span roadsides, buses and billboards across the capital as the outdoor sector gears up for the bumper contracts offered by the London 2012 Olympics.
JCDecaux and fellow out-of-home firms Clear Channel, CBS Outdoor and Titan have partnered with the London Organising Committee of the Olympic and Paralympic Games (LOCOG) to offer exclusive outdoor rights to Games' sponsors.
Lambert said the four companies had agreed with LOCOG to reserve outdoor sites for Olympics sponsors to book between March and June 2011 so non-sponsors couldn't "hijack" the sites.
JCDecaux sites in the capital include 20 'PrimeTime' digital billboards, digital airport sites, the superstructure Torch and Towers and iconic sites at the airport, including the Gatwick and Heathrow Welcome sites and Terminal 5's Global Gateways billboards.
