These numbers are not exact but provide an idea about the usage of the websites.
The things that is interesting is that all the major newspaper who hold commanding position in publishing also hold higher ranking for their web presence. However, their web presence is not as profitable as the old brick and mortar publishing.

Will they be the new news organizations who will be part blogger, part news aggregator and part investigative journalism?
