Facebook CEO Mark Zuckerberg announced today that the service he started in his Harvard dorm room roughly eight years ago now has over 1 billion monthly users (or over one-seventh of the world’s population).

“Helping a billion people connect is amazing, humbling and by far the thing I am most proud of in my life,” wrote Zuckerberg. “I am committed to working every day to make Facebook better for you, and hopefully together one day we will be able to connect the rest of the world too.”

The … video above was made for the occasion. Apple is obviously a huge partner with Facebook due to deep integration on both iOS 6 and Mountain Lion, and Zuckerberg talked with Matt Laurer on the “Today Show” about his relationship and admiration for the late Apple CEO Steve Jobs:

Zuckerberg also mentioned that current Apple CEO Tim Cook sent him an iPhone 5 and most people actually access Facebook on the mobile web rather than an app.

More big numbers, including 1.13 trillion likes, 140.3 billion friend connections, 219 billion photo uploads, 62.6 million songs played, 600 million mobile users, 17 billion location-tagged posts, were revealed in the data sheet (DOCX).
