Juice Box
From Wikipedia, the free encyclopedia
The Juice Box is a low cost Mattel multimedia player with a small screen (2.7" / 240x160px). It was marketed as a portable media player for kids. The player only played a proprietary cartridge format. Nickelodeon and Cartoon Network put some of their shows on cartridges. However, the small screen and poor quality (6 frames/second max) alienated most people. Furthermore, the device entered a crowded market. Its most potent rival was the Game Boy Advance, which not only had TV shows, but could also play video games. Thus many retail stores were left with a surplus of the device. Original retail price was about 70 dollars, but stores soon sold them at about two dollars apiece.
