I think you may want to consider switching to PBS for your news. I
believe they give you a full hour and I think the only commercials are
the ones at the very beginning and end of the show. Or go online for
your news. You may not have to endure commercials on those websites but
you may have to get used to hearing your news from unfamiliar faces.
I doubt ABC, NBC or CBS will ever ditch their commercials unless the FCC
forces them to do so. I can't see the FCC forcing that unless there's a
massive change in attitude there.
Historically, I believe the news started out very much as you're
describing: a public service, not intended to make money and simply
trying to inform people. I believe the news started out as only a 10 or
15 minute program too. But then the networks discovered that commercials
which aired during the news increased sales of the products advertised.
At that point, news became a profit center and remains one. I just don't
see the networks weaning themselves off that revenue stream voluntarily.
It's like asking a heroin addict to give up smack but harder: a heroin
addict might decide to kick the habit because of the physical damage
he/she is suffering from the drug use but I don't think the networks see
a downside from the ads.
Let's be honest here: the networks are in the advertising business.
That's where they make the money. The only way they can get people to
look at their ads is to throw in some interesting programming so they
bring in just enough sports, news, reality shows or scripted programs to
get people hooked, then they throw as many commercials at them as they
can get away with.
The broadcast networks have ramped up the number of commercials per hour
steadily over the years as people built up a tolerance for the number of
commercials they would endure before switching off the TV. In the 60s, a
typical hour had 8 minutes of commercials in it. In the 50s, I think
there were even less. Today, we have something like 18 or 19 minutes of
commercial every hour.
