The evolution of recorded music

posted by Jason Kottke   Jan 13, 2017

The Recording Academy has produced a series of three short and breezy videos on the history of recorded music, from the wax cylinder phonograph to cassette tapes to CDs to MP3s. Interest piqued, I went to read more about the history of the CD. When developing the disc, the physical size of it was dictated by Beethoven:

The two companies argued about what size, shape and technology the CD should support. It was eventually settled on a disc of 115 millimetres in diameter and 74 minutes worth of storage. Why 74 minutes? To fit Beethoven’s 9th Symphony, of course.

When the format was released in 1982, players cost $900 and CDs themselves were $30 ($2270 and $75 in 2016 dollars)1 and fewer than 100 individual titles were available for sale.

  1. And remember when movies on VHS cost up to $89.95? (If you paid that for a movie in 1984, that’s $210 in 2016 dollars. Suddenly those Hamilton tickets don’t seem so expensive.) Very few could afford to buy movies outright at that price…therefore, Blockbuster. See also the pricing for the original Nintendo.
