The BBC's Jonathan Fildes reports several tobacco firms signed up to a voluntary agreement to restrict direct advertising on websites in 2002.
Richard Desmond, the new owner of Channel 5, is in talks with Endemol to buy the rights to Big Brother, according to Media Guardian. But it says no announcement is imminent. This week's final drew 4m viewers, well up on last year's.
