Mechanically scanned television broadcasts began in 1928, and electronically scanned broadcasts began in 1936. Television was initially monochrome and color was introduced in the 1950s. It also used terrestrial broadcasting through ground-based transmitters. Later, cable television via overhead and/or underground wiring and then satellite television was introduced, both of which became common in the 1980s. More recently, since the mid 2000s, television has increasingly moved from analog to digital technology.
A Professional video camera (often called a television camera even though the use has spread) is a high-end device for recording electronic moving images (as opposed to a movie camera, that records the images on film).
