others have pointed to the apparent paradox that over the same period tha the Internet opens up the one to many world of mass media, that world itself has been consolidating. I just found this interesting info graphic from frugal dad on US media (thanks to my friend Faiza Ambah). While he tells the story front he point of view of an American media consumer, the same companies have grab sway across the rest of the world, including South Africa. (I speak as a father to a girl who's television viewing is monopolized by the Disney Channel). His sources are listed at the end of the graphic.
