Facebook founder and CEO Mark Zuckerberg has been ranked Number 1 in a list of the top 100 most powerful people in the media.

The MediaGuardian100, which is published annually by British newspaper The Guardian, is compiled based on candidates’ cultural influence, economic clout and political power.

Of Zuckerberg’s position, The Guardian writes: “Zuckerberg has been transformed from an awkward and unpromising geek into the world's richest and most famous twentysomething, listened to by world leaders.”

Only four years ago, Facebook made a humble appearance at number 100 on a list of the top 100 companies by the same newspaper. The social networking website has experienced particular growth in the past two years, with its revenue for 2011 expected to be $4 billion, double the figure for 2010. Zuckerberg himself has an estimated worth of $13.5 billion.

Zuckerberg is followed by another social media mogul—Twitter co-founder Jack Dorsey occupies the second place on the list.

The paper notes the fast moving nature of technology and social media, with a warning that “the web is a fickle friend” and “Facebook's position is precarious.” Google Chief Executive Larry Page occupies position three in the list, and it is expected his position may rise if his rivalling social networking site Google+ takes off.

Meanwhile, Apple co-founder Steve Jobs takes the Number 4 spot, Daily Mail editor Paul Dacre ranks seventh on the list, and Amazon founder Jeff Bezos is a new entry at Number 12.

Not surprisingly, the notorious phone hacking scandal has made a dramatic difference to the positions of News Corporation bosses. The positions of CEO Rupert Murdoch and Deputy Chief Operating Officer James Murdoch have both fallen, while Rebekah Brooks, the former News International chief executive, has disappeared altogether.
