History of Television

two distinct schools 

 the technology of Paul Nipkow’s rotating disks that supported a mechanical television system,

 electronic television system that used a cathode-ray tube developed independently by two inventors, Campbell-Swinton and Rosing.

Paul Nipkow (1860-1940), who invented the Nipkow disk in 1884, was the first person to discover the scanning principle that allowed small portions of an image to be analyzed and transmitted. However, it is unclear whether Nipkow actually built a working prototype of his television system

Electronic television is based on the development of the cathode-ray tube, which can still be found in modern television sets. Philo Farnsworth (1906-1971) was the first inventor to transmit a television image

In actual fact, the earliest proposal for color television was patented in 1904, while in 1925 Zworykin filed his proposal for an all-electronic color television system. Commercial broadcasting, however, started in the early 50s, a quarter of a century later

John Baird (1888–1946) is a researcher who is best remembered for inventing a mechanical television He created the first televised pictures of objects in motion (1924), the first televised human face (1925), color television (1928), stereoscopic television, and television by infra-red light 

Vladimir Zworykin (1889-1982), the inventor of the iconoscope, a transmission device, as well as the kinescope, i.e. the cathode-ray tube, in 1929,

 1929 Zworykin became the director of electronic research at Radio Corporation of America (RCA), and was later promoted to vice-president in 1947. Zworykin invented many devices including the scintillation counter

Louis W. Parker patented the “intercarrier sound system” in 1948, which is now used in all television receivers in the world.

The plasma display monitor was invented in July 1964 by professors Bitzer and Slottow and their graduate student Robert Wilson.
