I wonder what would happen if the Chinese started buying up these huge news conglomerates, maybe put Times in their back pocket, buy a bunch of agencies like Reuters. News is already very selective, depending on who owns the news media.
Social media, like twitter, facebook and so forth, prevent news from being totally hidden, but those outlets are very capricious in content. And, countries like China, the middle east, Russia can block access to those websites if they want to do so.
