Kelsey Campbell-Dollaghan: Surprise! Google just announced it has acquired the home automation startup, Nest, for $3.2 billion.

Source: "According Nest founder Tony Fadell, the acquisition won't affect the day-to-day operation of Nest, nor will it change anything about its branding. "Nest will stay Nest," says a company rep—though when has that ever truly been the case with a Google acquisition? Fadell explains his reasoning in a post on his blog, relayed to us through email but available online soon: "Google has the business resources, global scale and platform reach to accelerate Nest growth across hardware, software and services for the home globally. And our company visions are well aligned – we both believe in letting technology do the hard work behind the scenes so people can get on with the things that matter in life. Google is committed to helping Nest make a difference and together, we can help save more energy and keep people safe in their homes."
