The concentration of media ownership in the USA means that there is no 'Fourth Estate' in the United States. The digital divide of poor people without access to the www means there is no freedom of the press for almost 1/3 of Americans.
From Wiki: "The purpose of the first amendment to the US constitution was to encourage a free press as political agitator evidenced by the famous quote from US President Thomas Jefferson, "The only security of all is in a free press. The force of public opinion cannot be resisted when permitted freely to be expressed. The agitation it produces must be submitted to. It is necessary, to keep the waters pure."
