Comcast customers can now buy access to “House of Cards” season 1 through their cable set-top box and watch it across multiple devices — no Netflix subscription required. The cable giant struck a pact with Sony Pictures Home Entertainment, giving Comcast rights to sell the Emmy-winning first season of “House of Cards” through the recently launched Xfinity Store service. Netflix currently owns exclusive streaming rights to the Media Rights Capital-produced series, while Sony handles international and homevideo distribution. “HoC” season 1 has been available on DVD and via other EST services, including Amazon and Walmart’s Vudu. In addition, Comcast will add Sony titles to its early electronic sell-through service, which offers access ahead of the traditional VOD-rental window.
