Off the top of my head: 1) Mobile phones with the Fire phone - don't think this one requires any explanation. 2) Handmade goods with Amazon Handmade - Etsy's doing better than ever. 3) Travel with Destinations - don't think they've even tried to re-enter this market. I'm sure I could find more, but we tend not to remember a company's failures (unless they're spectacular) as much as successes.
