Way back, television was in its simplest form. Everything was live since the technology for recording programs hadn’t been invented yet. Basically, a camera caught the action and transmitted it via an electric current to a television set. Then, the antenna converted the electrical pulses back into the original images and sound. Now, modern technology has changed the way TV works. Today, we can even watch cable TV internet.

Cable television, formerly known as Community Antenna Television (CATV), is a system that provides TV programs to consumers by way of radio frequency signals that are transmitted to televisions through coaxial cables or digital light pulses. The way this system works is similar to the traditional over-the-air method. In other words, cable TV also made use of antenna in order to broadcast television. What makes the two different from each other is that cable TV utilized cables for sending signals rather than airwaves.

Pennsylvania was where it all started. Before, the only people who had television sets were those who lived on higher ground, or those who were close to the source of the program. This is because television signals during that time were actually transmitted over radio frequencies, which travel in straight lines. However, people who lived in the valleys of Pennsylvania came up with a creative solution to their viewing woes. By putting up antennas on the high spots, the tallest hills, around them, and then running cables down to their homes, they could receive the signals clearly. This paved the way for what we know now as cable TV.

However, more problems arose. One of the major problems they encountered was that the original system worked well only within short distances. Another was that signals sent through cables were subject to interference. In fact, the longer the cable and the farther the signal had to travel, the weaker it became. This resulted to a pretty distorted image in the television screen. In order to solve this problem, a series of amplifiers were installed along the way. Installing about one every one thousand feet distance increased the strength of the signal.

In today’s modern world, cable technology has developed so much since its birth back in the 1940s. Cable providers were importing their programming, assigning it to various channels, and re-transmitting it to their customers in their quest to cut down on interference and produce a clearer picture.

So if you’re having so much fun being able to watch cable TV internet, you can thank the people of Pennsylvania for introducing cable TV in the first place.
