With the invention of the Stereobelt in 1972 being the first portable music player it wasnt until 1979 when Sony brought to the world market the well known "Walkman" line of portable audio products. The price for portable audio is well below the original Sony Walkman price of $1000 putting personal audio in the hands of just about everyone. You can find mp3 players from $10 up to a few hundred dollars. A 8GB Ipod Nano will run you around $180.00 and is a large capacity player including full motion video for most music listeners. This low pricing combined with the excellent mass marketing campaigns of the Ipod from Apple has resulted in a second portable audio revolution. Only now just about everyone has access to a portable audio player.
