The end of objectivity looks at media standards through the lenses of scarcity thinking and abundance thinking:
The traditional premium on impartial journalism is a function of media scarcity: if you are the main or sole source of news you have an obligation to be balanced. That was certainly once true of America’s newspapers, which in a big country are distributed by city, almost invariably in ones or twos. And the rest of American media took its journalistic-standards lead from newspapers.But the UK is different in that it has long had a national newspaper market. Thus there was no news scarcity and newspapers differentiated themselves by taking sides.
