Back in 2001, there was a company who thought they could launch a sustainable business model around a file manager. They wrote the file manager itself, and figured they could profit from offering online services delivered through the file manager. However, the company ran out of money quickly, and wen they released version 1.0 of their file manager, they had to fire everyone, only to go down a few months later. That company was Eazel, and the file manager was Nautilus. Apparently, some saw this as the demise of the Linux desktop - others didn't.
