Home Box Office Inc. 

HBO was a pioneer in premium cable services, emerging in the 1970s a paid service offered in just a handful of cities. The cable provider grew in prominence in the ensuing decades, offering movies to subscribers often before they were available on VHS or other outlets. The company has created its own original television series and movies, as well as sporting events (most notably boxing matches). A move online has helped the company continue to grow. HBO now offers HBOGo, which allows viewers to watch popular shows including Game of Thrones via streaming video. Today, HBO has close to $1.8 billion in operating income each year.
