What people fail to realize is that Facebook/Google/Twitter/<insert every other digital advertising company that exists in SV> are solving the greatest business problem that exists - how to create a customer. Peter Drucker: There is only one valid definition of business purpose: to create a customer. It is the customer who determines what a business is. For it is the customer, and he alone, who through being willing to pay for a good or for a service, converts economic resources into wealth, things into goods. What the business thinks it produces is not of first importance—especially not to the future of the business and to its success. What the customer thinks he is buying, what he considers “value,” is decisive—it determines what a business is, what it produces and whether it will prosper. The customer is the foundation of a business and keeps it in existence. He alone gives employment. And it is to supply the consumer that society entrusts wealth-producing resources to the business enterprise. Because it is its purpose to create a customer, any business enterprise has two—and only these two—basic functions: marketing and innovation. They are the entrepreneurial functions.
