the first contact
The experience was replicated at the Royal Institution in London in 1926. In 1927 Baird managed to transmit the same image over 438 miles, using a telephone cable. In 1928 he did it again, this time from London to New York, over the airwaves. -
the first transmission
the BBC produced the first broadcasts of programming, which was not broadcast on a regular schedule. In 1930 the first simultaneous black and white audio and image transmission was made. -
electronic T.V
Vladimir Zvorykin invented the iconoscope in the RCA laboratories. It was an electronic tube that made it possible to replace all other television systems, thanks to an electronic mosaic made up of thousands of independent photoelectric cells in three thin layers. This advancement revolutionized the industry and allowed the emergence of electric television. -
color T.V
The adaptation of color televisions was completed in the 1970s, although monochrome televisions continued to exist for much longer. -
Digital T.V
Starting in the 1980s, television began to take its first steps towards digitization, driven by the digital revolution that the appearance of computers meant. This technology allowed a greater data transmission capacity, better resolution and the use of all the processing power of the computerized world.
