HBO SIGNATURE

Home Box Office (HBO) is an American pay television service, which is the flagship property of namesake parent-subsidiary Home Box Office, Inc., itself a unit owned by Warner Bros. Discovery. The overall Home Box Office business unit is based at Warner Bros. Discovery's corporate headquarters inside 30 Hudson Yards in Manhattan. Programming featured on the service consists primarily of theatrically released motion pictures and original television programs as well as made-for-cable movies, documentaries, occasional comedy, and concert specials, and periodic interstitial programs (consisting of short films and making-of documentaries).

HBO is the oldest subscription television service in the United States still in operation, as well as the country's first cable-originated television content service (both as a regional microwave- and national satellite-transmitted service). HBO pioneered modern pay television upon its launch on November 8, 1972: it was the first television service to be directly transmitted and distributed to individual cable television systems, and was the conceptual blueprint for the "premium channel", pay television services sold to subscribers for an extra monthly fee that do not accept traditional advertising and present their programming without editing for objectionable material. It eventually became the first television channel in the world to begin transmitting via satellite—expanding the growing regional pay service, originally available to cable and multipoint distribution service (MDS) providers in the northern Mid-Atlantic and southern New England, into a national television service—in September 1975, and, alongside sister channel Cinemax, was among the first two American pay television services to offer complimentary multiplexed channels in August 1991.
