It always happens first on records!

So, the paper sleeve in one of these old LP's has an interesting marketing ad on them:

Records give you more of what you want

Back in 1972, when this was printed, the main competition to the LP was reel-to-reel tape and 8-track. Vinyl, of course, had the lowest overhead and highest profit margin of all manufactured music, so obviously the labels wanted people to buy their music on vinyl whenever possible.

Who knew that 10 years later, a shiny silvery disc would be introduced that would relegate most records to the dust bin...

Gotta love old out-of-date marketing materials...
