Sony launched the world's first consumer CD player, the CDP-101, in Japan in 1982

The Dawn of Digital Audio

On October 1, 1982, Sony introduced the world's first consumer CD player, the CDP-101, to the Japanese market. This event marked the beginning of the compact disc digital audio era, offering a new medium for music consumption. The CDP-101 was priced at JPY 168,000, which translates to approximately $1,060 today, or about $3,700 when adjusted for inflation.

Initial Release and Technical Aspects

The initial launch was limited to Japan because Sony's tech partner, Philips, was not ready with its CD100 player for a simultaneous worldwide release. The CDP-101, while groundbreaking, had some technical limitations, such as using a single DAC for both stereo channels due to the high cost of converters at the time, leading to an approximate 11 μs sync difference between channels.

Six months later, in March 1983, CD players became available to consumers in the U.S. and Europe.

Addressing Previous Audio Limitations

Before CDs, home audio systems relied on vinyl records and cassette tapes, which were susceptible to degradation from dust, scratches, warping, and variable tape quality. CDs promised a durable, laser-read digital format that would not wear out, along with features like instant track selection and skipping.

Content Availability and Market Adoption

Sony collaborated with CBS to ensure 50 CD albums were available in Japan at the CDP-101's debut. However, the 'western' launch six months later was supported by only 16 titles. The widespread adoption of CDs as a hi-fi standard occurred in the mid-1980s, as player prices decreased and the catalog of available CD albums expanded significantly.
