You’re right. This post appears to be closer to when the tech was invented vs when they became mainstream. CDs were invented in 1982 but usage really didn’t take off until adoption in the 90s.
Cassettes weren't big until the eighties and cd's were nineties. USB? Sure, maybe. Spotify didn't become available for the US until 2011 (I waited patiently for that). And vinyl has definitely been coming back for quite some time now.
And vinyl has been hot again for decades. Especially when it was the only medium for DJ’ing - before digital turntables became a thing. Major cities have been littered with hipster vinyl shops for like 20 years.
