TV news is wonderful entertainment, because entertainment best delivers
the most eyeballs to the commercials whose sales are the whole point of
commercial television.

Some old people remember when the networks competed for credibility to
lend prestige to their organizations. Problem is, really excellent
news is a guaranteed money-loser. In the days of Edward R. Murrow, it
was understood that news was not to be judged on profitability, on the
same model that big automakers will turn out an impressive
low-production sports car at a loss to lend prestige to the nameplate.

That's simply no longer true anywhere in US TV news. News programs are
expected to turn a profit. These considerations are incompatible with
accuracy, balance or depth in a population with a short attention span.

If you want to be informed, alternate between at least 7 or 8
newspapers from at least a few different countries.

If you want to be entertained, try a good fictional show instead.

It's hard to say what TV news is good for, but for being informed...
not so much.
