Why cant anyone make an mp3 player that has AM Radio

You are all wrong about AM antennas. I've been using the Sony SRF-M95 & M97 for years, and they have developed a system wherby the earplugs act as the antenna. This makes the unit about the size of a matchbox & delivers excellent sound. All the manufacturers need to do is to add a small MP3 unit and it would still be half the size of an iPod.

It's all a matter of (perceived) commercial need. The target market for mp3 players is 14-30yo.This demographic matches FM listeners. AM radio listeners are traditionally 35yo+. Manufacturers won't start making AM mp3s until they perceive sufficient demand
