Push Play 1: the CD

As we've seen, this was still the era of the LP record.  The beginning of the end of that dominance took place on March 8th, 1979 when Phillips first demonstrated the compact disc player.  The format for the actual disc had not been finalized, but that would start to take shape later in the month when Phillips would partner with Sony to develop a standard format.  (Fun fact: they had to change the size of the disc when Sony insisted it must be large enough to contain all of Beethoven's 9th Symphony, which was 74 minutes.)

It would take a few more years for this technology to hit commercial, but when it did, the CD would revolutionize they way we listen to music.  And now it's the CD's turn to fend off new technologies. We'll hear about that soon...
