Discman was a brand name used by Sony for their portable CD players. The first Discman, the Sony D-50 or D-5 (depending on region), was launched in 1984. The Sony brand name for Discman changed to CD Walkman, initially for Japanese lineups launched between October 1997 and March 1998,[1] and then entirely in 2000. Discman and CD Walkman players were discontinued at the beginning of the 2010s when they lost popularity with the general public.
