Well the CD is 30 years old. On 1st October 1982 the first commercial CD player was announced in Japan. It was from Sony (a CDP-101, c.£450) and coincided with Billy Joel's 53nd Street album being released on CD. That was followed by Sony's first portable CD player in 1984.
The ideas of CD started early as 1974 with Phillips. From whom the term originated... and evolution of the "compact cassette". While the default music format has now moved on to digital the CD was also the pre-cursor to the visual formats of DVD and Blue-Ray.
When CD arrived, many commented about "the silence is positively deafening" with the absence of background hiss and crackle of vinyl. Interesting of course that these days, music producer are often inserting that background crackle for an added effect.....
