How Did Zuck Get Rich?

In 1991, Tim Berners-Lee wrote 9,600 lines of code which converted the first web page. He sold it on Sotheby's for like 12 million bucks; I wish I could have bought it. Zuck created a business where he created an app that uses TCPIP every single day and gathers all his customers' data to give away something for free. By the way, if it's free, you're the product. And then he sells your data. Same thing like 23andMe. People pay money to give your DNA to a company who then sells the DNA to a drug company for a thousand dollars.
