Sony's first CD player, the CDP-101, changed the way people listened to music. Music became crisp and clear because it lacked the noise associated with tapes and vinyl records. However, this medium was initially expensive and not many people could afford it. The CDP-101 sold for around $674 dollars, and the first American album available on CD was Billy Joel's "52nd Street." CDs at the time cost around $15.
Not long after Sony introduced the CDP-101, companies in Europe and America began producing CD players. It was then that the prices began to fall and the technology became available to more people.Learn more about Inventions
