This is a story not much known about but it's been confirmed quite recently. Some years ago (Khosla, an Indian billionaire VC) was helping GOOGLE to sell their entire business to EXCITE for about $1 million dollars. EXCITE turned it down - maybe this is one of the worst decision in corporate history.
Over subsequent years, Excite went to crap. Today GOOGLE is a website everyone knows about and is now worth $167 Billion dollars.
