Now Playing: 03-26-14 Marketplace - What is Facebook thinking?

Mark Zuckerberg has been out shopping again: Facebook paid $2 billion for Oculus, a small virtual reality headset company. Random purchase or strategic move? And with its acquisition of WhatsApp and other companies earlier this year, is Facebook being a venture capitalist, or is there a long-term, coherent plan to future-proof itself with a stake in these areas of technology? Meanwhile, movie ticket sales are down but movie ticket receipts are up, thanks to inflation over the years and the higher prices for 3-D. We look at the business model of movie theaters and how ticket revenue fits in with the revenue from popcorn and candy bars. And, this is how the end arrives: The cessation of the slow drip-drip-drip of saline solution, because there is no saline solution. No jolting-back-to-life injection of nitroglycerin, because there is none. Why common everyday medical supplies can suddenly be hard to find.
