PALO ALTO, Calif. (AP) -- Facebook is introducing tools that will make it easier for people to separate their online friendships into different groups and copy all the personal information they have posted on the website.
The new features will start rolling out to Facebook's more than 500 million worldwide users Wednesday.
Facebook founder Mark Zuckerberg unveiled the changes during a press conference that marked his first public appearance since last Friday's debut of "The Social Network," a movie tracing Facebook's origins and evolution. The movie depicts Zuckerberg as an isolated, treacherous genius. Zuckerberg told reporters he wouldn't discuss the critically acclaimed film, which has drawn large audiences so far. He has previously scoffed at the movie as a gross exaggeration of his 6-year-old company's history.
