Sony Portable Audio in 1998

By 1998, Sony’s portable audio ecosystem had reached a point of stability. MiniDisc was no longer experimental. It had matured into a complete system with refined hardware and a clear use case, particularly in markets where its advantages were fully understood. At the same time, Discman and cassette Walkman remained deeply embedded in everyday listening.

This stability, however, masked a deeper shift. The traditional model of portable audio was still built around physical media, whether tape, disc, or magneto-optical formats. But new forms of digital audio were beginning to appear, detached from any single physical format. Early MP3 players and computer-based music storage introduced a different idea: that music could exist independently from the device used to play it.

What defines 1998 is not disruption itself, but the moment just before it. Sony had successfully built and sustained multiple portable audio systems at once, each refined and widely used. But the foundations of that model were beginning to change. The next phase of personal audio would not be defined by formats alone, and 1998 stands as one of the last years where the old structure still held together.
