The Television Portal![]() Electronic television, which was much more practical and successful in the long run, with a better picture, was based on the cathode ray tube. The English inventor Alan Archibald Campbell-Swinton did important work in 1907, as did Boris Rosing, a Russian scientist, working independently, however American Philo Farnsworth is credited with the first working electronic television system, which he demonstrated in 1928. 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 were introduced. More recently in the 21st century, television has increasingly moved from analog to digital technology.

Selected picture![]() Pixelization is a video- and image-editing technique where an image, or part of it, is blurred by displaying part or all of it at a markedly lower resolution. A familiar example of pixelization can be found in television news and documentary productions, where vehicle license plates and faces of suspects at crime scenes are routinely obscured to maintain the presumption of innocence, as in the television series COPS.
