in 1884 Paul Gottlieb Nipkow, a 23-year-old university student in Germany, patented the first electromechanical television system which employed a scanning disk, a spinning disk with a series of holes spiraling toward the center, for rasterization. The holes were spaced at equal angular intervals such that in a single rotation the disk would allow light to pass through each hole and onto a light-sensitive selenium sensor which produced the electrical pulses. As an image was focused on the rotating disk, each hole captured a horizontal "slice" of the whole image.
Nipkow's design would not be practical until advances in amplifier tube technology became available. The device was only useful for transmitting still "halftone" images-represented by equally spaced dots of varying size-over telegraph or telephone lines.[citation needed] Later designs would use a rotating mirror-drum scanner to capture the image and a cathode ray tube (CRT) as a display device, but moving images were still not possible, due to the poor sensitivity of the selenium sensors. In 1907 Russian scientist Boris Rosing became the first inventor to use a CRT in the receiver of an experimental television system. He used mirror-drum scanning to transmit simple geometric shapes to the CRT
No. Radio came first.
Phone came before the TV.
Technically the very first camera (out in 1826) and the very first video camera (came out around the 1950's)
There have been millions of hours of television shows broadcasted since the first television show was aired. People can watch a variety of shows 24 hours a day.
the first colour tv came out in 1928.
Driving licence - 1903 Tv licence - 1940 So obviously driving licences came out first! :)
2007
Let me answer this with a question. Which came first, the chicken or the egg?
Video recorder came first, TV stations were using them in the 1960s.
Sony
1973
