What was the first mp3 player?

Question

When did it first appear, how many MB did it have and what company made it?

Answer 1

The world's first mass-produced hardware MP3 player was Saehan's MPMan, sold in Asia starting in the late spring of 1998. It was released in the United States as the Eiger Labs MPMan F10/F20 (two variants of the same device) in the summer of 1998, a few months before the Rio.
