Entertainment giant Sony [SNE], creator of innovative products such as the Walkman and Playstation, has a market capitalization of 18.5 billion dollars. But not all of their products have been successes. Remember BetaMax? Yeah, that was Sony.
There were other Sony attempts that have since fallen into obscurity: AIBO, PSX/PlayTV, the eVilla Network Entertainment Center. The list is long.
And yet, Sony has not only survived, but grown ever more successful. Why? Because they didn't let their failures define them.
