Launch date: 2004

Fatal flaw(s): Poor interface and design, lack of commercial push 

Can you call something a fail if you never really expected it to succeed? Sure you can. With Roc-A-Fella at the top of its game, and Roc-A-Wear doing equally well, Dame Dash thought it'd be a good idea to expand his empire into other areas. He partnered with a liquor company to market Armadale vodka, for instance. After that he decided to tackle consumer electronics with a company called Roc Digital. Under Roc Digital he would release two MP3 players: a 20 GB Rocbox and a 256 mb Rocbox that would come with exclusive Roc-A-Fella music. Despite the lure of exclusive tracks, the Rocbox failed miserably.
