A good point to remember, but Google has done and continues to do much more than these companies. Its current financial position puts it in a much more defendable fortress than these past companies. The amount of money Google has put into streamlining its operations are, in my opinion, is its real competitive advantage. Google can crawl and analyze the web faster than pretty much anyone (my company is trying to make this is un-true ;) ), which creates a significant barrier to entry.
