What are values and business functions in IT corporations?

Facebook has celebrated its one-billion-active-subscriber population to convince how it has generated the customer-based online-ad-monetizing platform. One of unimpressive performances is to experience a share price drop since its IPO in May, 2012, dissuading investors and analysts over how Facebook can survive in a long-run. Now it has refocused on so-called potential-customer-selling transaction to business firms that want to approach specific customers who have used Facebook pages and accessed to Facebook’s features. Everyone is waiting for real revenue results.
