How are they a publisher in this instance? They are not creating/publishing their own content. The NY Times publishes their own content and just like TV, other Internet services/sites and radio broadcasts paid ads. None of them have or ever will verify the veracity of each ad's content. Im just curious how Facebook is different then TV, radio, print and all other Internet services? No one has answered this question.
