Cablevision Systems has hired Gardner Nelson & Partners to create both print and broadcast advertising promoting the company's video services and the continued evolution of its iO: Interactive Optimum digital cable television service. Cablevision serves approximately 3 million cable customers in the New York metropolitan area, more than one million of which are iO digital cable customers. The first execution in the campaign, which launched this week, features a fictional politician named Beekins who conducts an extensive filibuster by listing all of the channels available with iO Digital Cable Service. Upcoming executions will focus on specific benefits of iO such as on-demand viewing and an expansive array of HD programming available at no additional charge. The agency was chosen in closed review.
