Charles P. Ginsburg Charles Ginsburg led the research
team at Ampex Corporation in developing the first practical videotape recorder
(VTR). In 1951, the first video tape recorder (VTR) captured live images
from television cameras by converting the information into electrical impulses
and saving the information onto magnetic tape. Ampex sold the first VTR
for $50,000 in 1956.The first VCassetteR or VCR were sold by Sony in 1971.

P. Ginsburg Charles Ginsburg led the Ampex research
team that developed a new machine that could run the tape at a much slower
rate because the recording heads rotated at high speed, allowing the necessary
high-frequency response.

Video Recording In the early days, film was the
only medium available for recording television programmes. Thoughts turned
to magnetic tape, which was already being used for sound, but the greater
quantity of information carried by the television signal demanded new studies.
During the 1950s, a number of American companies began investigating the
problem.
Television Cameras In the 1920s, American engineer,
Philo
Taylor Farnsworth devised the television camera, an image dissector,
which converted the image captured into an electrical signal.
Television Cameras The pick-up tube is the main element
governing the technical quality of the picture obtained by the camera.
The first electronic cameras using iconoscope tubes were characterised
by very large lenses, necessary to ensure enough light reached the pick-up
tube.
Video Stills - Digital
Photography The still video or digital camera
(the Sony Mavica single-lens reflex) was first demonstrated in 1981. It
used a fast-rotating magnetic disc, two inches in diameter, recording on
it up to 50 images formed in a solid-state device in the camera.
The images were played back through a television receiver or monitor, or
printed out.
The
History of Recording Technology Tape Recording Technology -
Audio and video magnetic recording has had greater impact on broadcasting
than any other single development since the invention of radio/TV transmission
itself.

VHS - Video tape in a large cassette
format introduced by both JVC and Panasonic around 1976. This has been the most
popular format for home use and video store rentals, however, it will be replaced
by mini dv tapes and dvds. VHS stands for Video Home System.
