Facebook is the undisputed leader in websites and mobile apps. Although the Internet is comprised of over 1 billion websites the majority of time is spent on only a handful of them, and Facebook is the most active of all of them. Americans spend more time on Facebook than Google Search and YouTube combined. One out of every five minutes spent on mobile phones is spent on the Facebook app. People spend more time on their phones on Facebook than they do sending text messages and making phone calls combined!
