The basic idea of television is "radio with pictures." In other words, where radio transmits a sound signal (the information being broadcast) through the air, television sends a picture signal as well. While mechanically scanned systems were experimentally used, television as a mass medium was made practical by the development of electronic camera tubes and displays. Beginning in 1989, however, television markets in rural areas began to aggregate, allowing these rural networks to broadcast over a larger area, often an entire state, and become full-time affiliates to one specific metropolitan network. There are various bands on which televisions operate depending upon the country. For the receiving apparatus to reconstruct the image, synchronization information is included in the signal to allow proper placement of each line within the image and to identify when a complete image has been transmitted and a new image is to follow.

Wireless technological form of broadcasting became the original form of distributing media, be it entertainment, news or information, etc. The concept of scanning, which established the possibility of using only a single wire or channel for transmission of an entire image, became and remains to this day the basis of all television. The television industry's changing of aspect ratios is not without difficulties, and can present a considerable problem. What this means is that filmed newspapers or long captions filling the screen for explanation are cut off at each end.

This is especially common with low-power television stations, and in recent years, even more so for stations that used this revenue stream to finance their conversion to digital broadcasts, which in turn provides them with several additional channels to transmit different programming sources.
