HBO Now is an over-the-top subscription video on demand service operated by American premium cable and satellite television network HBO. Officially unveiled on March 9 and launched on April 7, 2015 the service allows subscribers on-demand access to HBO's library of original programs, films and other content on personal computers, smartphones, tablet devices and digital media players. Unlike HBO Go, HBO's online video on demand service for existing subscribers of the linear television channel, HBO Now is available as a standalone service and does not require a television subscription to use, targeting cord cutters who use competing services such as Netflix and Hulu.
