CD sales peaked at about a billion units in 2000. The last data I saw (2013) showed that it was the latest of a dozen straight years of declining sales, bottoming out at +/- 200 million units. Since 2010, the avg annual decline has been small, so it appears that CD sales aren't really being "phased out", they're just slowly dying off. At what point do "major labels" stop releasing CDs altogether? Does it matter? It's pretty clearly a dying format.
I don't have data from the 1960's, but, by comparison, in the '70s, LP sales peaked at +/- 200 million units. Obviously, that was a smaller (unit) market for recorded music than we have today. Contrary to what many here seem to believe, however, the LP was not "killed off" by CD, it was killed off by cassettes, which displaced LP sales at basically a 1 for 1 rate up to 1985. Then CD joined the party and LPs essentially disappeared as a meaningful piece of the market.
As a practical matter, LP is still dead. Unit sales might make up 1% of the market and dollar sales might be 1.5 to 2%.
