In the first major mobile programming deal between a cellular carrier and a broadcast network, Sprint Nextel and the Walt Disney Company signed a multi-year agreement Tuesday that will enable Sprint wireless customers to access ABC and Disney television programming on their mobile phones. The pact is viewed as a key step beyond existing offerings, marketed by carriers such as Verizon Wireless, that provide short video clips to customers or live TV shows that are available only at specific times. For $20 per month, Sprint Nextel customers will be able to view a wide portfolio of full-length ABC television shows, including Desperate Housewives, Grey’s Anatomy and Lost, on demand. Each episode will be made available one day after its broadcast air date, and subscribers will be able to access the four most recent installments of each series. Customers will also be provided access to several mobile “linear” channels, such as an ABC news channel that provides live news on a 24-hour basis and a Disney channel that provides full-length episodes from the cable network. Proclaiming that Disney’s goal is to “[find] new ways to connect viewers to the content they want and brands they love on the platforms they choose,” Disney-ABC Television Group president Anne Sweeney praised the deal as one that “not only provides new viewing opportunities for consumers, but also gives advertisers another platform to reach viewers.”
