Behind every successful product lies a problem in search of a solution. The inspirational problem, in the iPod's case, involved the pitiful state of the young MP3 player market in the late 1990s.

Portable MP3 players had been around since the mid 1990s, but Apple found that every one on the market offered a lackluster user experience. Steve Jobs had a strong term for gadgets like that: "crap". Everyone at Apple agreed.

Flash memory-based players of the era held only about a CD's worth of songs. Hard drive players held far more, but were relatively big, heavy, and they sported difficult-to-navigate user interfaces that did not scale well when scrolling though thousands of songs.

Moreover, most portable media players (PMPs) used the pokey USB 1.1 standard to transfer music from a host computer to the player, which made the user wait up to five minutes to transfer a CD's worth of songs. When moving thousands of songs, the transfer time could shoot up to several hours.
