Liberty is working with international and national content providers, such as YouTube, Facebook and Twitter, to develop applications for its standards-based "App Store," in which subscribers will be offered a catalog of web-based apps and widgets that integrate with the TV user interface. Liberty Global is reaching out to potential content partners and third-party application developers and will soon launch a software developers' kit.
Liberty is currently executing field trials on Horizon in the Netherlands and later in the year will move to consumer trials. Commercial launch is planned for Q1 2012 at UPC in the Netherlands, with UPC Cablecom in Switzerland and Unitymedia in Germany following soon thereafter. Horizon will be added to the company's existing lineup of advanced digital products, and existing digital customers will be offered an upgrade package at launch.
