Creation of the Facilmile system
Facsimile transmission systems for still photographs pioneered methods of mechanical scanning of images in the early 19th century. Alexander Bain introduced the facsimile machine between 1843 to 1846. Frederick Bakewell demonstrated a working laboratory version in 1851. -
First transmission
In England in 1878, John Loggie Baird, a Scottish amateur scientist, successfully transmitted the first TV picture. -
Invention of the Color TV
Among the earliest published proposals for television was one by Maurice Le Blanc in 1880 for a color system, including the first mentions in television literature of line and frame scanning, although he gave no practical details. -
Cathode rays
In 1897, J. J. Thomson, an English physicist, in his three famous experiments was able to deflect cathode rays, a fundamental function of the modern CRT. The earliest version of the CRT was invented by the German physicist Karl Ferdinand Braun in 1897 and is also known as the Braun tube. It was a cold-cathode diode, a modification of the Crookes tube with a phosphor-coated screen. -
Electronic TV was demonstrated
Philo Farnsworth demonstrated his electronic television in San Francisco, in 1927. -
The CRT TV was invented
Using J. J. Thomson's Cathode ray discovery, a new form of tv was developed and became very popular. Vladimir Zworykin was also experimenting with the cathode ray tube to create and show images, but did not comeplete it before Thompson. -
Digital TV
Digital television is the transmission of audio and video by digitally processed and multiplexed signal, in contrast to the totally analog and channel separated signals used by analog television. Digital TV can support more than one program in the same channel bandwidth.
