The Data Discman (Japanese: データ ディスクマン, Hepburn: Dēta Disukuman) is an electronic book player developed and marketed by Sony Corporation, first introduced to Western markets in late 1991 or early 1992. The device targeted U.S. college students and international travelers but achieved limited commercial success outside Japan. In Japan, it was positioned as part of Sony’s broader "Discman" brand, originally used for portable CD players such as the D-50 released in 1984.
