It's sort of weird to realize that I've been alive and purchased every music format--except wax cylinders!! Even "Extended Play" 45-rpm 2-disc albums (they weren't very popular) of which I owned a couple, and pre-recorded open-reel tapes. And, lest readers think I'm 100, the 78s I bought in the 1950s were all electrical recordings. The era of acoustical 78-rpm recordings (done with a huge horn that moved a diaphragm that moved the stylus) ended in the late 1920s.
I'd never thought about it, but I'm pretty much in the same boat - 78s, 45s, LPs (mono, stereo, and a few Quadraphonics) - still have 3000 of them, pre-recorded reel-to-reel tapes, pre-recorded cassettes, CDs, SACDs, DVD-As, DVDs, HD-DVDs, Blu-ray. I don't think I ever owned an 8-track or any media. It's life was so short lived that I must have missed it. However, when I was in radio, we used cartridges (stereo only, I believe) for commercials, etc. Does that count?
Missed Laser Discs too.
I've got some 78s from the 30s and 40s, but it wasn't me who bought 'em. They were my parents.
