List Of Experimental Television Stations
This page is a list of the experimental television stations before 1946. After 1945 (in the United States) the television frequencies were opened up to commercialization and regular broadcasts began. Regular broadcast television start dates vary widely by country; in many regions, initial broadcast video deployment was delayed due to mobilisation for World War II. (Note: The listing of current broadcast channels for these stations is not up-to-date as many low-VHF stations have moved to UHF frequencies as a result of digital television transition. This is less of an issue in the United Kingdom because of its all-UHF system, but most early US broadcasters were on affected channels before analogue shutdown. Very few full-service North American broadcasters remain on physical channels VHF 2-6 digitally due to impulse noise problems and strict limits on maximum transmitted power at these frequencies.)

Television Station
A television station is a set of equipment managed by a business, organisation or other entity, such as an amateur television (ATV) operator, that transmits video content and audio content via radio waves directly from a transmitter on the earth's surface to any number of tuned receivers simultaneously. Overview Most often the term "television station" refers to a station which broadcasts structured content to an audience or it refers to the organization that operates the station. A terrestrial television transmission can occur via analog television signals or, more recently, via digital television signals. Television stations are differentiated from cable television or other video providers in that their content is broadcast via terrestrial radio waves. A group of television stations with common ownership or affiliation are known as a TV network and an individual station within the network is referred to as O&O or affiliate, respectively.

Mechanical Television
Mechanical television or mechanical scan television is a television system that relies on a mechanical scanning device, such as a rotating disk with holes in it or a rotating mirror drum, to scan the scene and generate the video signal, and a similar mechanical device at the receiver to display the picture. This contrasts with vacuum tube electronic television technology, using electron beam scanning methods, for example in cathode ray tube (CRT) televisions. Subsequently, modern solid-state liquid-crystal displays (LCD) are now used to create and display television pictures. Mechanical-scanning methods were used in the earliest experimental television systems in the 1920s and 1930s. One of the first experimental wireless television transmissions was by John Logie Baird on October 2, 1925, in London. By 1928 many radio stations were broadcasting experimental television programs using mechanical systems. However the technology never produced images of sufficient quality to become ...
