It's roughly 240 lines resolution on an analog tape medium.
* It is quite amazing the technological advancements in video and in audio since the era of VCR tape machines and cassette tapes, WoW!
But we were happy, so that was the most important. ...And we had turntables too, and we still have them today...that, is truly amazing!
The LP album is the only audio medium along with the reel-to-reel tape (less so though) that are still today the "superior" formats.
Today is Dolby Vision with Dolby Atmos, 4K UHD, Dual laser projectors, Tidal hi-res music downloads, much more advanced DACs from AKM and ESS, ultra high-end turntables with phono stages, and open reel-to-reel tape machines reconditioned.
Music and Movies keep rolling one way or another with a much improved "connection".
Flat panels are the norm, they are light, larger screens (in the old days a 28" TV was big, up to 36-40" later on, and today it's a 60-65" and up to 84" ... roughly double everything).
From 240 lines we are now @ 4096 x 2160.
Look @ cell phones, from the huge walkie-talkie size type to now a mini computer in our palm.
Look @ PCs, from none (when we were playing outside chasing the ball and the girls) to the robots we became.
The car industry; from horses (animals pulling chariots, Egyptians), to today's teleportation (computer virtuality; instant 25,000 miles across the globe).
