Hbo

HBO was the first cable network to originate as a non-terrestrial broadcast TV network. In reality, it all started in 1965, after cable pioneer and visionary Charles Francis Dolan won the franchise to build a cable system in lower Manhattan. The new system, named Sterling Manhattan Cable by Mr. Dolan, was the nation's first urban underground cable system. Instead of stringing cable on telephone poles and using microwave antennas to receive the signals, Sterling laid underground cable beneath the streets of Manhattan because television signals were blocked by many tall buildings. Time Life, Inc., in the same year, purchased 20 percent of Dolan's company.
