Facebook is not looking at breaking up the social media giant, its COO Sheryl Sandberg said on Wednesday. Sandberg was taking questions from journalists, one of which referred to FB co-founder Chris Hughes's recent op-ed piece in New York Times that suggested FB be "separated into multiple companies".

Hughes, who joined hands with Mark Zuckerberg to launch FB from their Harvard hostel 15 years ago, had argued that the firm's size had given its CEO Zuckerberg "staggering" influence that is "unprecedented and un-American".

Acknowledging concerns of increasing influence of big companies as hers, Sandberg said regulations were important. Emphasising enhancement of regulatory frameworks to combat privacy issues, she said the company is to set up a regulatory content board with zero interference from her or Zackerberg.

"We're working with leaders around the world on laws," she said. As for transparency, she said FB files transparency reports every six months, and from next year it will do it every quarter. She evaded questions on a Wall Street Journal report last week that "Facebook had uncovered emails that appear to connect Zuckerberg to potentially problematic privacy practices at the company".
