Murdoch may be many things, but one thing he has not been accused of is incorrectly overestimating the tastes of the public.
The public wants bums 'n' boobs on page 3? The public gets them. The public wants to vicariously listen into the grief of the bereaved and the families of the missing? Then the public will get that, too.
Every one of their regular readers and buyers has a personal, individual responsibility for their choices - choices which have encouraged Murdoch to pander to them.
