They have their own distribution network of newspaper carriers to reach subscribers a few hours after their deadline. They usually rely on the postal network and reach subscribers a few days to a few weeks after their deadline.

They use a distribution network of booksellers to reach buyers a few months after the author finished the manuscript.
