First TV ever
John Logie Baird was a Scottish engineer and inventor of the world's first working television system in Hastings, England, in 1923. A public demonstration subsequently took place in Selfridges, a department store in London England, during March 1925. The system was successful enough to become commercialized, and the BBC began the world's first regular television broadcasts in January 1929, using Baird's system.

electronic TVs
On the other side of the Atlantic, Philo Farnsworth was working on similar ideas. His first demonstration of television was in 1927. Like Baird's system, it was electro-mechanical, but by 1929 he had eliminated the moving parts of his system to create the world's first fully electronic system. -
TV signals
In 1927, Baird transmitted a long-distance television signal over 438 miles (705 km) of telephone line between London and Glasgow; Baird transmitted the world's first long-distance television pictures to the Central Hotel at Glasgow Central Station. -

In 1928, Baird demonstrated the first color television. Like his monochrome television, it used rotating discs to build the image. The three discs added red, green and blue light together to create a full-color image. Although cumbersome, it demonstrated the principles of color television that have remained in use to this day. -

During the same time period, Vladimir Zworykin, a Russian engineer working for Westinghouse in Pittsburgh, was working on television. He was granted several patents, but didn't quite reach a full working television system. However, in the 1930s he developed the "Iconoscope," a form of cathode ray tube to capture moving images electronically. This paved the way for better-quality image capture. -
TVs ready to use
Since those pioneering years of the 1920s, the development of television has been rapid and consistent. The BBC adopted a fully electronic system of television in 1936 and Baird's system fell into disuse after that time. -
Selling of TVs in the U.S
The 1940s saw dramatic improvements in the sensitivity and quality of camera tubes. The 1950s marked the first color broadcasts in the US, while Britain and Europe began seeing television in color during the 1960s.
