LOCOG is looking for an integrated advertising and marketing services agency to assist it with its above- and below-the-line communications in the run-up to the Games in 2012.
The appointed agency will develop the creative identity and look for the Games, and work on ticket marketing. It will also work on LOCOG's key initiatives and events over the next three-and-a-half years.
London 2012's commercial director, Chris Townsend, and the head of brand and marketing, Amanda Jennings, are heading the pitch.
Townsend said: "The next three-and-a-half years will see LOCOG's marketing and communications come to the fore. It is important that people feel part of (the Games) and can contribute - and our marketing campaigns will be central to this."
Interested agencies must register their interest via London 2012's procurement process, the CompeteFor service, before 22 January.
