Social media is a powerful and revolutionary form of communication that is young and living. Facebook has over 1.23 billion monthly active users, with over half of the world's population under 30 years old. Social media has changed how people meet each other, with 1 in 5 couples meeting online and 1 in 5 divorces blamed on Facebook. It has also changed marketing, with the Ford Explorer launch on Facebook generating more traffic than a Super Bowl ad.
