As Mark Zuckerberg continues to expand his empire, for the very 1st time, number of mobile daily active users on the social-networking giant, Facebook, has surpassed that of desktop daily active users. ARE YOU Surprised??

Facebook‘s monthly active users on mobile devices increased 57% year over year to 680 million. The world’s biggest social network also added its mobile revenue made up 23 percent of its overall advertising revenue, up from 14 percent in the last quarter.

As of late December, 680 million users were actively accessing the social app on smartphones every month, up 57% from a year earlier and the world’s No. 1 social network doubled its mobile advertising from the previous quarter. People hate ads, right?

“Today, there is no argument that Facebook is a mobile company,” CEO Mark Zuckerberg said during a conference call with financial analysts. Building new “mobile experiences” will be a focus in 2013, The Menlo Park, Calif., company said.

However, Facebook will not make a phone, Zuckerberg said. Instead it will continue to focus on enhancing the user experience across all types of devices. Even if the company were to sell 10 million phones, that would only represent 1 percent of users, “which makes no sense,” Zuckerberg said.

Zuckerberg also talked up Facebook’s new search tool, Facebook Graph Search. “It’s good for lots of things that you wouldn’t use a traditional search engine for,” he said. “It could turn into a meaningful business for us.” For now, Facebook is refining “Facebook Graph Search” and working on rolling it out to all users, Zuckerberg said.

• Facebook’s total advertising revenue was $1.33 billion, representing 84 percent of the company’s total sales and it’s total annual revenue increased 37 percent to $5.09 billion.
• According to research firm eMarketer, the mobile advertising business nearly tripled last year to $4 billion and is expected to exceed $7 billion in 2013.
• Facebook was the most used mobile app across iOS and Android devices in the United States in 2012.

 ”A couple of quarters ago mobile revenues were zero percent of our ads revenue,” Chief Financial Officer David Ebersman said. “Now we’re up to 23 percent and believe there’s a lot of growth ahead of us.”

“Two quarters ago, we really had no mobile revenue,” Ebersman said in an interview. “In the course of a pretty short period of time, we’ve dramatically ramped up our ability to monetize mobile.”

“Marketers are realizing more and more that Facebook is one of the best places to reach customers on mobile,” Facebook COO Sheryl Sandberg said.
