With a large amount of foot traffic from well-heeled consumers in a captive environment, airports are a natural choice for digital out-of-home video, and the marketplace has been heating up over the last year. In the latest development, CNN Airport Network added its 50th major airport partner when it signed a new carriage deal with Spokane International Airport. In 2011 Spokane International Airport was visited by over 1.5 million passengers, making it equivalent in traffic to airports in Palm Springs and El Paso. For its part CNN Airport Network features daily news from CNN and HLN, entertainment programming from HBO, TBS, TNT and TCM, and live sporting events from the NFL, NBA, MLB and the NCAA Men’s Basketball Championship. CNN Airport Network also recently renewed contracts with Memphis International Airport, Miami International Airport, and Phoenix Sky Harbor International Airport. As noted, 2012 has seen a lot of activity in the airport advertising space. After launching a new airport division, Titan Airports, in April, Titan has signed up several new airport partners. In August, Titan announced the signing of a five-year contract for the exclusive right to sell advertising in Westchester County Airport in White Plains, NY, just north of New York City, and in October the company signed a five-year deal with John Wayne Airport in Orange County -- the second-largest airport in southern California, with around 9 million passengers per year. Meanwhile, in May Clear Channel Airports partnered with SapientNitro to launch a new version of its “FlySmart” mobile travel app, which provides a variety of information including flight status, gate location, baggage claim, current weather conditions, parking availability, security wait time and ground transportation options. Its new features include customized content from participating airports, flight push notifications and detailed information from Bing Maps to help travelers navigate restaurants as well as retailers and baggage claims.
