I'd forgotten about CED!
The Capacitance Electronic Disc format was commonly known as "videodisc", leading to much confusion with the contemporaneous LaserDisc format.
Also RCA released the 45 (in 1949? one year after 33 LPs) with a big hole in the middle and their player thus couldn't play LPs or 74s, so the "spider" was invented and the Labels then produced 45s with knock out centres.
Tapes are inherently "for ever" more expensive to duplicate, never mind the material & manufacturing costs. The mass produced CD, DVD, BD are pressed, which is why 1890s record discs better than phonograph cylinders. Even MO drives, like in the PS Portable, could also read pressed discs, though those never caught on for music for PSP.
RCA had lost the plot by the 1960s.
Actually the transistor was 10 years old then.
Then by maybe 1986 RCA were gone. Originally Victor and created HMV in UK and Japan Victor Company (JVC still uses a version of the Nipper logo in Japan).
CED and Philips Laser disc both invented in mid 1960s. CED was grossly inferior.
I remember reading about it and the article was sceptical. Only the size and marketing power of RCA allowed them to sell as many as they did,
Quote:From what I've heard CED had a lot of quality issues.Yes. The early idea of selling them like LPs in a sleeve had to be abandoned.
