Apple iPods were launched with the catchy caption

It is said, “1000 songs in your pocket," that was widely accepted by the music lovers around the globe. The portable media players designed and marketed by Apple Inc. named iPods were launched in October 2001.

The first public demonstration of the iPod kiosks took place in New Jersey in March 1998, and the commercial use started in January 2000. The trademark was registered by the USPTO in November 2003, and Grassy assigned it to Apple Computer, Inc. in 2005. Apple iPod were constructed in the way that they are able to carry MP3, AAC/M4A, Protected AC, AIFF, WAV, Audible audio book and Apple Lossless audio file formats ensuring perfect and excellent musical entertainment for the user.

The main and important difference between MP3 players and iPods is that simply copying audio or video files to the drive with a typical file management application does not permit iPod to properly access them. User must use particular software that has been specifically designed to transfer media files to iPods, to make the files playable and viewable.
