There are many claims to the first CATV system, but only one thing is for certain; it originated in the United States and, according to one famous recollection, cable television had its beginning in 1948 in Mahanoy City, Pennsylvania. Community antenna television, as it was then called, was invented by John and Margaret Walson out of a necessity to bring television to their customers. They owned The Service Electric Company, a company designed to sell, install, and repair appliances. When they started selling television sets in 1947 their Mahanoy City customers were reluctant to buy because of reception issues. This particular region of Pennsylvania had difficulties picking up the stations in nearby Philadelphia due to the mountains that surrounded them.
To solve this problem, Walson installed an antenna on a utility pole that he placed on a local mountain top. It allowed him to demonstrate that the televisions could pick up good broadcasts coming from some of the Philadelphia stations using modified signal boosters and cable to connect the antenna to his store. So, in 1948, he charged a small fee and connected the antenna to several of his customers' homes as well, marking the beginning of the cable television business.
