| 释义 |
Walson, owner of a Mahanoy City General Electric appliance store, needed to solve problems receiving signals from Philadelphia television stations, which were blocked by the mountains surrounding the town. Walson erected an antenna on a utility pole on a local mountaintop that enabled him to demonstrate the televisions in his store with strong broadcasts coming from the three Philadelphia stations. He connected the antenna to his appliance store via a cable and modified signal boosters. He then connected several of his customers who were located along the cable path. This was the first community antenna television (CATV) system in the United States. Walson's company grew over the years, and he is recognized as the founder of the cable television industry{{Citation needed|date=May 2010}}. He was also the first cable operator to use microwave to import distant television stations{{Citation needed|date=May 2010}}, the first to use coaxial cable to improve picture quality{{Citation needed|date=May 2010}}, and the first to distribute pay television programming{{Citation needed|date=May 2010}}. His descendants now own Service Electric, which is a family owned cable TV provider serving Pennsylvania and Northwestern New Jersey.[1] External links
