========================
As I said: LD was DEVELOPED long before VHS. That is a fact.
Sales in test areas started in 1977.
MCA had working prototypes in 1969.
I have this magazine:

also:
Laserdisc technology, using a transparent disc, was invented by David Paul
Gregg in 1958 (and patented in 1961 and 1969). By 1969 Philips had developed
a videodisc in reflective mode, which has great advantages over the
transparent mode. MCA and Philips decided to join their efforts. They first
publicly demonstrated the videodisc in 1972. LD was first available on the
market, in Atlanta, on December 15, 1978, two years after the VHS VCR and
four years before the CD, which is based on laserdisc technology. Philips
produced the players and MCA the discs. The Philips/MCA cooperation was not
successful, and discontinued after a few years. Several of the scientists
responsible for the early research (Richard Wilkinson, Ray Deakin, and John
Winslow) founded Optical Disc Corporation (now ODC Nimbus), and that company
is still the world leader in optical disc mastering technology

etc etc.....
Now who is the idiot?
