CPA proposes installing digital screens in airport washrooms across the BAA estate. This would allow for dynamic advertising that can be updated regularly. CPA would manage the technology and sell advertising, providing BAA with a new revenue stream and communication tool at no cost. A partnership would involve CPA installing 1800 screens using wireless technology. Advertisers could purchase campaigns as short as 5 seconds. BAA would have veto power over ads and communication benefits like updates on services. The proposal aims to generate revenue for BAA while providing an engaging new media option for advertisers.
