This April, the social network Mark Zuckerberg began coding in his Harvard dorm room launched Facebook Home. Neither an operating system, nor a phone, Home is downloadable software supported on several Android devices (to start) that takes over Google's original operating system and offers users a Facebook-centric experience. Status updates and notifications pop up on the lock screen, and a new unified messaging feature makes texting others -- Facebook users or not -- a streamlined experience. If anything, Home represents a small sneak preview into how the mobile experience could be a much more social one.
Wal-Mart retook the top spot, Berkshire Hathaway made the top five, and Apple grew enormously.
