Cable Television has come a long way since it was first made available in 1948. When Cable TV first began to reach out, it was not a method of receiving additional channels, and was only really used by people that lived in areas where they were not physically far from the over-the-air transmitters, but lived in a ravine or a mountainous area where television signals had trouble penetrating. However, as time went on, and the government deregulated the cable TV industry in 1972, original programming became pervasive throughout cable, and now is the sole reason to acquire cable TV instead of over the air.
Another huge change in more recent times is the shift from analog cable signals to digital cable signals. The addition bandwidth that digital cable provides allows for many more channels to be transmitted over the same cable that was laid long ago. This new digital technology also requires to have a special digital cable box, but in return provides a much better, high definition quality video. Of course, the price of this superior cable is also much higher, and in some places the cable company requires their customers to buy many more channels for digital cable.
