Nothing like a little historical context to go beside your latest updates.

However the Toynbee or the Gibbon of the future adjudges what happened to American society, he will need to reckon large with the impact of radio and television. By the 1950s, TV had become the greatest new instrument of political and social influence in the nation. How that happened, how TV became both a shaper and a creature of politics, both a maker and a prisoner of public tastes, is most simply told as the story of one broadcasting network, of its founder and indomitable chairman, William S. Paley, and the men who helped make CBS into Paley's golden candy store.

David Halberstam has written that story as part of a larger work in progress about centers of power in America and the ways they have been affected by science, technology, and modern communications.

Don't forget part 2:

The advent of the half hour news program made television the major source of news for many Americans and the only source for a dismayingly large number of them. This vested in broadcasters awesome responsibilities and a sense that they had ventured into a political minefield. In the first installment of his two part examination of the growth of broadcasting, television journalism, and the CBS network in particular, David Halberstam showed how the medium became both a shaper and a creature of politics, both a maker and a prisoner of public tastes.

In this installment he tells how three Presidents influenced and were influenced by TV, how TV made Vietnam into an electronic war, and how, reluctantly, it dealt with the Watergate tragedy.

Then go watch Network, or at least read this original NYT review, published the same year this Halberstam piece was published. (There are plenty more to choose from, if that one doesn't suit you.)
