The Japan-only launch was partially because Philips, Sony's partner in the development of the CD format, was unable to meet the original agreed launch date. Rather than agree to a full postponement, Sony agreed to delay the launch of the format outside Japan by six months.The Philips CD100 launched in November 1982, although early Philips players contained some Sony components.

In line with the agreement, the system was launched worldwide in March 1983.
