Well, back then the capital markets were all about value investing. And if someone in 1999 told you that a publicly traded company could run losses for 15 years straight and be 'successful', you'd have looked at him as though he were a fool.

'Valuation' these days seems to be less about determining the free cash flow of a company's operations. It's the promise of great innovation that's just around the corner. Or, more likely, it's the promise that a bigger company will acquire this company at a markup above whatever you paid.
