Nothing brings a community together like the collective glow of its television .in spring of 1948, American john Walson (1914-1993) installed community antenna television, bringing the wonders of the cable television to his customer. During the 1950s television was the primary medium for influencing public opinion

Cable television originated in U.S. simultaneously in Oregon , Pennsylvania  and in Arkansas in 1948 to enhance the reception of over the air television signals in mountainous or geographically remote areas   

Walson and his wife Margaret, owners of the services electric company of Mahanoy city, Pennsylvania, came up with cable television as a way to help their customers pick up signals blocked by nearby mountains. Walson decided to take his service literally to new heights by climbing to the top of a mountain and planning an antenna. Using cable and signal boosters, he connected the antenna to his appliance store. Along the way he dropped the signal directly off at his customer’s home, thus creating the first community antenna television system

Community antenna television, now knows as cable Tv is found 60 percent of U.S. homes and throughout Europe. The first cable system consisted of a large antenna to capture the signal amplifiers arranged throughout the service area. As the signal moved along the cable it weakened forcing the designers to implement amplifiers at regular intervals, but amplification added noise and distortion to the signal and created a potential place for the signal to be completely lost.

Soon thereafter, cable was fortified as more and more channels were added. Microwave transmitters and receivers were used to capture distant signals, giving cable provide more channel choice. The wave for sofa bound channel surfers was the fast approaching tidal proportions.
