Why did Laserdisc failed?

Came across this informative Youtube video but like to point out some things he didn't know or forgot.  He mentioned quality between off the air and Laserdisc picture performance as "not that much difference". Maybe if one lives next door to a TV transmitter but where I live A HUGE DIFFERENCE!

When I got the CED (different format but same quality) the video quality was like night and day.  Didn't know a TV picture could ever be THAT CLEAR :o, and that was with an RF connection.  Became better with a video input connection.

Mentioned why were there were stereo jacks on the first generation units, no movies were broadcast in stereo at the time.  Well the forward thinkers whom developed the Laserdisc system knew some movies were in stereo early as 1960.  Theatre systems were Westrex 4 channel magnetic, Super Panavision 70, Todd AO and by the late 1970's Dolby System which basically was an opitical version of Westrex 4 channel (this is not Dolby Stereo).  Sooner or later after movies were released to video, stereo will soon follow.  One had to connect any video unit regardless of format to a home stereo system for the dynamic sound.  Early stereo TV sets were fair at best.

The author of the video forgot to mention again from his first Youtube clip, Laserdisc was the first with Digital sound a few years before DVD's came on the scene.  

The advent of compact disc gave a resurgence of LD starting during the early 1990's which had the CD quality audio along with CX noise reduction.

 

Laserdisc was the first format to offer 2.35 widescreen.

Later a few models solved the annoying issue of having to flip the disc every hour, can play both sides without removal.

 

 

 

 

Footnote, the small electronic device on a piece of wood is a phono oscillator (broadcaster). 1:33 time frame.

I took notice to the bottom of the webpage of my last post regarding the Jack-O'-Lantern sun.  Someone think this is some indicator of impending doom or recently at an airport, aliens.

Hole Punch Cloud, rare but nothing to worry about.  Rarer to have one with an embedded rainbow.  Just another example how wonderful nature can be so if anyone see one, don't freak out it's not the end of time. :wacko:

Imagine seeing this at night from the ground!

A short lived TV series explained this back during the 1970's solved the V shape UFO's as geese fliying at night in formation.  The oil film on their feathers reflected ground light to the observer. If lighting is strong enough and the observer far enough away will not hear the honking.. Very difficult to gauge distance from any pinpoint of light at night.

That article and post headline makes it looks like it's the Native Americans HERE whom done the sacrificing. :angry: Should had stated the indigenous people of Central and South America by which the practice of human sacrifice is well known.

PJ Media is known to utilize strong loaded words (wording that attempts to influence an audience), in publishing misleading reports.

I don't think he minds if the information is incorrect if it supports his notions of "racial inferiority."
