Facebook founder Mark Zuckerberg has unveiled changes to member profile pages and said the movie "The Social Network" got "hugely basic" things wrong about the origins of the site.

Zuckerberg, in an interview yesterday with the CBS show "60 Minutes, said he turned down an opportunity to sell Facebook to Yahoo! for one billion dollars four years ago and made it clear he is in no hurry to take the company public.

The 26-year-old Facebook chief executive also defended his approach to the privacy of the social network's more than 500 million users, saying "we never sell your information."

"Advertisers who are using the site never get access to your information," he said. "It's against all of our policies for an application to ever share information with advertisers.

"Now, do we get it right all the time’ No!" he said. "But it's something that we take really seriously."

The new profile pages highlight recent pictures in which a member has been "tagged" in a bar at the top of the page along with biographical information such as where a member is from, where they went to school, their relationship status and where they work.

"People love photos," Zuckerberg said. "Photos originally weren't that big a part of the idea for Facebook, but we just found that people really like them, so we built out this functionality."

The new profile pages should be available to all of Facebook's users by early next year, Josh Wiseman, a Facebook engineer, said in a blog post.

Facebook members can highlight their most important friends on their new profile, create new groups of friends or share activities and interests such as favourite musicians and sports teams.

Speaking of "The Social Network," Zuckerberg said "we took the whole company to go see the movie" and "I actually thought it was pretty fun.

"It's pretty interesting to see what parts they got right and what parts they got wrong," he said. "I think that they got every single T-shirt that they had the Mark Zuckerberg character wearing right. And they got sandals right and all that.
