I'm gay and proud of it, says Apple chief Cook

Apple CEO Tim Cook says he's proud to be gay.

The public declaration, in an essay written for Bloomberg Businessweek, makes Cook the highest-profile business CEO to "come out".

He said that while he never denied his sexuality, he never publicly acknowledged it, either. The chief executive said that for years he's been open with many people about his sexual orientation and that plenty of his Apple colleagues know he is gay.
