Where can I find statistics on the use of analog tape from say 1980 to
present. Ideally I'd like to be able to see the percentage of
recordings and know what years saw a decline in use and ho rapid it
was.

I remember an ad in the early 90's that siad "90% of top ten hits are
still recorded to analog tape".

Maybe they just made ths statistic up, but if it's actually tracked,
I'd like to try to find actual statistics.

Well... Yes did a CD in 1984 that was all digital (computer type stuff).
