Same here. But basically it shows that "value" as considered by economists, has moved from physical assets to things like software, expertise, marketing brands & other 'soft' stuff like intellectual property. And with that, companies considered most valuable (market cap) have changed from ones that manufacture physical goods, to the .com advertising / cloud computing / online shopping giants of today. I'm piling the "socials" onto the "advertising" heap here... ;-)
