Zuckerberg: 1 Billion on Facebook Almost "Guaranteed"

After passing the 500 million user mark, Mark Zuckerberg says it's only a matter of time before Facebook reaches 1 billion users. In an interview with The Guardian, Facebook's CEO also said an initial public offering was in the company's plans.

• Zuckerberg, who said he had recently met Prime Minister David Cameron "for just a minute [when] he was busy rolling out the budget", also admitted that one day he could see Facebook floating on the stockmarket - just not anytime soon.

• He added that there was "no chance" Facebook, which has cracked the 500 million user mark, would hit 1 billion this year but argued that "it is almost a guarantee that it will happen".

• "If we succeed [in innovating and remaining relevant] there is a good chance of bringing this to a billion people" it will be interesting to see how it plays out," he said speaking to two packed auditoriums - one via video link - at the Cannes Lions International Advertising Festival.

• Facebook's global domination is almost complete, he said. "We are down to just four countries where we aren't the leading social network."
