In my opinion Laserdiscs weren't a joke, specially cus in my mall there were quite a few stores that sold them (Specs and Suncoast had huge racks of them) and with 10,000 US titles available from SEVERAL mail order stores, and Laserdiscs being aimed more at the movie fan market many of those were de creme de la creme (Criterion special editions, deluxe Universal and MGM boxes, Disney Super Aluminium boxed editions including Hardcover coffee table books, 12" x 12" booklets, OST CDs and of course the discs themeselves in CAV for complete full motion manipulation of animation with a jog wheel, from NUMBERED frame by frame still motion to 3x fast speed (72frames per second) totally fluid motion forward and reverse shown at NTSCs (live looking) 60Hz refresh rate and loads of supplements (some of them never showing up on DVD). It's true the picture was analog and it's slighly softer than DVD on the horizontal resolution dpmt. but both DVD and LD use the same NTSC 480 pixel based vertical resolution (vertical scanning lines on a TV systen by their discrete nature are the equivalent to digital pixels)
And on the sound department well appart from having the ability to have different soundtracks/commentraries their Stereo Digital uncompressed PCM soundtracks are better than DD 2.0 stereo 13 to 1 compressed soundtracks and of course LD's were the first and only place for a few years where you could get discrete 5.1 multichannel soundtracks like DolbyDigital 5.1 and DTS 5.1 (the latter always in it's full maximum bps rate)
And of course, presenting Widescreen  movies in their OAR was originated and stablished in LDs  
On top of that there were the Japanese LDs which weren't region coded 

 and played perfectly w/o any trouble, so  there was a looooooot of programming available in addition to the US titles (just ask mvealf 

)
LDs were 'round even BEFORE CDs.
Heh if they had done double layer Digital mpeg2 Laserdiscs instead of DVDs we would have had 100GB DLDs with SuperHDTV since 7-8 years ago 
and Blue-Ray LD's would be 600GBs... 
Amd in you added mpeg4 compression you coulld fit TEN 70mm movies with all their resolution
and..
