As the networks increased the number of programs that they aired, however, officials at the Federal Communications Commission (FCC) grew concerned that local television might disappear altogether. The technology of television has evolved since its early days using a mechanical system invented by Paul Gottlieb Nipkow in 1884.

Signals can also be delivered by radio from satellites in geosynchronous orbit and received by parabolic dish antennas, which are comparatively large for analog signals, but much smaller for digital. About five years after the end of the Second World War, Canadian entrepreneurs looked ahead to their future. Television is now delivered in a variety of ways: over the air by terrestrial radio waves (traditional broadcast TV); along coaxial cables (cable TV); reflected off of satellites held in geostationary Earth orbit (direct broadcast satellite, or DBS, TV); streamed through the Internet; and recorded optically on digital video discs (DVDs) and Blu-ray discs.

Currently, licensed national or provincial networks must be carried by all cable providers (in the country or province, respectively) with a service area above a certain population threshold, as well as all satellite providers. In 1880 a French engineer, Maurice LeBlanc, published an article in the journal La Lumire lectrique that formed the basis of all subsequent television. Of course, the first device that we today would recognize as television involved the use of Cathode Ray Tubes (CRTs).

John Baird becomes the first person to transmit moving silhouette images using a mechanical system based on Nipkow's disk. This contrasted with the North American situation. This enables TV to get closer to the aspect ratio of modern widescreen movies, which range from 1.66:1 through 1.85:1 to 2.35:1. Improvements have been made continuously since that time, and television technology changed considerably in the early 21st century. Cable and satellite providers pay the networks a certain rate per subscriber (the highest charge being for ESPN, in which cable and satellite providers pay a rate of more than $5.00 per subscriber to ESPN).
