File:Apple Music Event 2008 - 4G iPod Nano Introduction

Description
Introduced in September 2008, the iPod nano (4th Generation) doubled the capacity of the previous model, and marked the return of the original nano form-factor. Whereas the "fat boy" iPod nano had been built wider to accommodate a 4:3 screen for viewing video, the iPod nano (4th Generation) added an accelerometer which allowed the iPod to be rotated 90 degrees for 4:3 video viewing.
