...example, despite its increasing use of fiber-optic-cable systems that carry far more conversations at lower cost, AT&T is stuck with millions of miles of old-fashioned copper wire and coaxial cable. Also on its books are millions of old dial telephones, built to work for 40 years but less versatile than newer high-tech models like its Touch-matic, which automatically dials up to 15 numbers...
...CATV came into being-and still functions as a mere extension of network television. While network television has been using CATV to compensate for the deficiencies inherent in broadcasting, they have, however, missed out on the special properties of cable TV. Cable TV, because it transmits signals through coaxial cables, can operate at much lower transmission costs and has the potential to carry hundreds of channels. In these terms, it is easy to see how the way in which the network hogs the electronic frequencies forces it to operate as a highly centralized industry. Where network television must derive...
...commission. Conventional TV broadcasters do have very real grievances, for CATV could be piratical unless properly regulated. It was started to bring television to isolated or poor-reception areas. CATV entrepreneurs raised hilltop antennas, plucked the signals of distant channels from the air and then relayed them, generally by coaxial cable, direct to subscribers' TV sets...
Beyond that, CATV could change the country's way of life. Its copper coaxial cables, though larger than telephone cord, have 1,000 times the communications capacity. Washington willing, the U.S. could be transformed into what some call "the wired nation." Within ten years, CATV's two-way conduits could provide set-side shopping and banking, dial-a-movie service, a burglar and fire watch, and facsimile print-outs of newspapers or even library books...
...reception for the TV signal. From Parkes the signal was relayed overland to Sydney, flashed to the Moree Earth Station 200 miles to the north, beamed up to the Intelsat communications satellite 22,300 miles above the Pacific Ocean, relayed to Jamesburg, Calif., passed by microwave ground signal and coaxial cable to Houston and finally transmitted to New York for distribution to individual television sets. In spite of the separate systems and the incredibly circuitous routes, both sight and sound arrived in precise synchronization in millions of homes around the world...
