The first systems to communicate over long distances with electrical signals utilized wire or cable. The telegraph, teleprinter, and later, telephone, required a physical connection to the "wire" to send or receive those communications. It also meant that the "wire" owner not only could restrict service, but could charge for the connection.
When it was discovered that radio frequency waves could also carry those same electrical signals, but without the wired connection, it was naturally called "wireless" communication.
The transmission of sound (voice and music) programs intended for reception by the general public came to be called broadcasting, from the term used of the scattering of seed. Anyone within the signal range of the transmitting, or broadcasting, station, with the appropriate reception device (receiver) could listen in. And they did. Radio broadcasting quickly caught on with the public in the 1920's, '30's, and '40's.
Methods of also broadcasting pictures were rapidly developing at the start of WWII. Put on hold during the war years, television quickly became popular after the war. Television broadcasting was much more involved and expensive than radio, however, and was generally limited to large population areas. Many small towns and cities found that they could not afford to operate a television broadcast station, nor were they always able to receive adequate (or any) signals, especially if they were in a location, such as a valley, that blocked the VHF signals, or rendered them so weak as to be unusable.
Those broadcast signals might be quite adequate at some higher elevation, however - if you happened to have an antenna located there. Re-enter wire and cable communications. Set up an antenna in a favorable reception location, connect a cable to it, and run the cable to your home down in the valley. Or to many homes in the valley, for that matter. Just keep stringing that cable. Community Antenna Television (CATV) was born.
Again, the owner of the system could not only place restrictions on who could use the service, but could charge for it. Money could be, and was, made in CATV service. Competition to construct CATV systems was quite keen, so much so that regulation soon followed. As with many public utilities, franchises could be granted - or denied. It quickly became necessary for Federal Government as well as local oversight of CATV service, especially because the broadcast signals carried on the CATV systems were under Federal Communications Commission oversight.
Programming from existing television broadcast stations was not the only issue, however, as the final legislation was developed in the 1970's. A community, or a CATV system owner, for that matter, could insert television broadcasts that originated from even the simplest television source. These signals could take the form of a program schedule guide, a local "Bulletin Board" service, or the origination and broadcast of local community sports, educational, governmental, religious or other programming. Rules were formulated to require franchisees to provide channels for certain local community programs. Educational institutions and governmental bodies could then access the entire cable (CATV) audience without the expense of operating a large broadcast transmitter system.
The local competition was quite vigorous in the early 1970's and a CATV franchise was operating in the Newark community by the time WGSF ceased broadcasting in 1976. Now, the Newark City School District had to establish a television origination operation that could be placed on one of those Educational CATV channels stipulated in the franchise.
