WHEN DID DIGITAL TECHNOLOGY BEGIN?

I thought an historical outline of the digital medium and its beginnings would be of interest to Gon members. Any additional info to add would be appreciated.
1. 1937. British scientist Alec Reeves files the first patent describing pulse-code modulation.
2. 1943. Bell Telephone Labs develops the first digital scrambled speech transmission system, SIGSALY.
3. 1957. Max Mathews of Bell Labs develops the process to
digitally record sound via computer.
4. 1967. The first digital audio magnetic tape recorder
was invented by Technical Research Labs of Japan's NHK
broadcasting network. A 12-bit 30 kHz stereo device using
a compander noise process to extend the dynamic range.
5. 1970. James Russell patents the first digital-to-optical recording and playback system, which would later lead to the compact disc.
6. 1972. Denon invents the first 8-track reel to reel digital recorder.
7. 1975. Thomas Stockham, through his company, Soundstream,
makes the first digital audio recordings from a digital audio recorder he designed, which became the first commercial recorder available to the pro industry.
8. 1978. Sound 80 Records of Minneapolis records "Flim and the BB's" directly to digital before pressing the vinyl LP.
9. 1979. The first digitally recorded vinyl record of popular music "Bop Til You Drop" by guitarist Ry Cooder.
10. 1980. Sony makes the first compact disc and takes the cut out perforations pattern from player piano paper music rolls from 100 years earlier and duplicates the pattern to the surface of the compact disc and the perforations from the player piano roll become pits on the disc for the laser to read.
11. 1980. Denon builds the worlds first commercial CD player for studio's.
12. 1980. Pioneer makes the worlds first commercial Laser movie disc and by 1986 produced laser movie disc players for the retail market.
13. 1982. Sony releases the CDP-101, the first CD player for the retail market in the Spring, followed by the Philips/Magnavox players in the Fall.
14. 1990. Digital radio begins in Canada using the L-band.
15. 1991. Digital audio tape is developed by Alesis called
ADAT, (Alesis Digital Audio Tape).
16. 1996. Sony develops the DVD and starts selling players in Japan which started selling in the USA in 1997. The minature laser disc, the DVD, was the death of the large laser disc which had 400 lines of horizontal resolution and the smaller DVD had 500 lines and superior audio.
17. 2000. In October, Sony develops the blu-ray disc prototype and continues to develop through April 2003 and releases blu-ray players in June 2006.

An interesting thread. As Nvp pointed out, the origins of digital technology are old. Very.

An abacus is a digital technology, and it's been around since Mesopotamia. It was also used in ancient Greece, Rome, Persia, China, and India. The abacus is a good example of what makes a technology "digital," namely that it performs computations with data represented in discrete values.

Speaking of computation, I don't think anyone has mentioned Alan Turing, who was instrumental in the development of computationalism in computer science. The Turing Machine was a hypothetical device that could simulate the computational processes of virtually any digital technology.

The history of digital technology is awe inspiring, in an Arthur C. Clarke kind of way.

Correction:

You mention digital audio tape came out in 1991. DAT had been out since 1987.

One more tangential note:

A lot of related technology came out of Bell Labs ca 1970, when they developed WDM (wavelength division multiplexing), and, later, DWDM (dense wavelength division multiplexing) to increase the potential capacity of fiber optic telecom cables. Today, many of the optical elements of various digital sound technologies have some roots in that research.

Correction..I mentioned the first digital audio magnetic tape recorder wass developed in 1967 by Technical Research Labs of NHK Broadcasting in Japan. I neglected to mention,
(my fault!) that same year Denon collaborated with Tech Research/NHT and developed the first digital tape. They took 2 inch video tape and converted to a quadruplex format for digital recording so it could record at a very high rate. Denon made this digital tape available in 1972 to be used with their 8-track digital recorder they put out that year. Soundstream came out with their own 1 inch digital tape in 1976 which they developed in 1975 for their digital audio recorder they designed.

1958-1959: Invention of the integrated circuit, by Jack Kilby of Texas Instruments, for which he later won the Nobel Prize in Physics; and a few months later, independently, by Robert Noyce of Fairchild Semiconductor, who co-founded Fairchild Semiconductor and (at a later date) Intel.

Kilby's IC was Germanium-based. The one developed by Noyce was the first Silicon-based IC, and incorporated other improvements that increased its practicality.

Note: To an electrical design engineer, "IC" = "integrated circuit," not "interconnect cable." :-)
