ABSTRACT
Experiments in television began in the 1880s. Early thinking about how to send pictures using electricity was divided between two methods: Mechanical scanning and electronic scanning. Broadcast television signals were sent from a station’s antenna to receiving antennas connected to television sets. Anything that records or plays back a television image will have to change to accommodate 4K or 8K content. Commercial television broadcasting was ready to begin business in 1941, but US involvement in Second World War essentially halted its development. In the early days of television, National Broadcasting Company and Columbia Broadcast System were both financially strong, had highly rated VHF affiliates, and an inventory of programs that were set to make the transition from radio to television. The early days of television had some challenges, including blacklisting people working in the industry who supposedly had communist sympathies. Cable television started out in the late 1940s as a small-time system to provide rural audiences with television programming.
