I totally missed out on these, so imagine my surprise when I stumbled upon video discs of Star Trek: TMP and Superman: The Movie at a yard sale. I bought them, even though I had no way of playing them. Still have them. For a quarter...why not?
Interesting that RCA used Trek to advertise their new technology. RCA owned NBC, which aired Star Trek, so they used Trek to advertise color TVs a decade earlier, in the 60s.

They did the same thing even earlier with the television show Bonanza.
We had one of these before a VCR. A very flawed format, after a few views, the discs would start skipping (as they had physical contact with a needle as opposed to a laserdisc read by a laser). We would rent discs and some would skip like crazy. My dad ended up trading it in for a VCR, a wise decision!
We had one of these prior to our first vcr...in fact we still had it and my mom's discs up until 5 or 6 years ago...I know we had Friday the 13th on a disc I can't remember the overs we had..

WAIT, WHAT?!? I just assumed this was a laserdisc! I had to go back and do more than skim the ad. How did a needle transmit video? Was the quality really bad?

...undulations in the groove under the stylus directly controls the capacitance between the stylus and the conductive carbon-loaded PVC disc. This varying capacitance in turn alters the frequency of a resonant circuit, producing an FM electrical signal, which is then decoded into video and audio signals by the player's electronics.
Seems it took about 17 years to develop the technology into a product and by the time it hit the market, VHS was ready to be "the standard" for home video....for a lot of reasons. (way more to it than that, but that's the short version)

Thanks. I assumed it worked similarly to a vinyl audio record, also translating into video signals, but it's hard to imagine an acceptable signal.
