Sony's MiniDisc was one of two rival digital systems, both introduced in 1992, that were targeted as replacements for the Philips Compact Cassette analog audio tape system: the other was the Digital Compact Cassette (DCC), created by Philips and Matsushita. Sony had originally intended the Digital Audio Tape (DAT) to be the dominant home digital audio recording format, replacing the analog cassette. Due to technical delays, the DAT was not launched until 1989, and by then the U.S. dollar had fallen so far against the yen that the introductory DAT machine Sony had intended to market for about $400 in the late 1980s now had to retail for $800 or even $1000 to break even, putting it out of reach of most users.
