Mypod
Wikisimpsons - The Simpsons Wiki
The Mypod, created by Mapple, is able to store hundreds of songs and videos to be listened to or watched. Lisa got one from Krusty as the screen was too small for him to watch things on. They are created by Steve Mobs who also owns Mapple. Lisa found out the hard way that you can get into a lot of debt by downloading too many songs without realizing.
Behind the Scenes
It is an obvious parody of the iPod.
