1900s

1908, Alan A. Campbell-Swinton came up with the idea of combining the rotating disk as the transmitter and the cathode ray tube to create a picture at the receiver. This was the initial concept that led to building the first TV.

1925, John Logie Baird, even though Nipkow developed the idea of the rotating disk, Baird made the first mechanical TV. He was able to transmit silhouette images of moving people over a wire circuit.

1927, Philo Farnsworth built an electronic TV (Image Dissector). He abandoned the old concepts of a mechanical TV and a rotating disk, using the concept of an electron scanning gun instead of the
rotating disk.

1950, Radio Corporation of America (RCA) Sequential Dot Color System, Instead using three color filters, RCA used three tubes with each having a different color filter, i.e., red, blue, and green, for the scan. Then, the sample was transmitted to three different cathode ray tubes (CRTs), i.e., red, blue, and green, the three were combined in a monitor to create
color TV.
