On October 1, 1982, the first CD player was released. Sony was responsible for the development of the CD in 1982, and that same year, Japan saw the release of the first CD player, the Sony CDP-101. It had a price of 168,000 yen upon release and was later released in North America in 1983 for a price of $730. It was only launched in Japan at first because Philips, Sony's partner in the development of the CD, could not meet the original agreed release date. Instead of a full postponement, Sony agreed to delay the launch of the music format outside of Japan by 6 months.
