"There is always been"? Seriously?
I'm going to assume you meant,
"There has always been political commentary passed off as news." But, no, not really, not even remotely like it is today, where commentary is passed off as news as a matter of course. There were television and radio broadcasts dedicated to commentary, and programs dedicated to news, and it was clear and unambiguous which was which. News programs (and newspapers) gave the Five Ws of Who, What, When, Where, Why, and How.
- Who is it about?
- What happened?
- Where did it take place?
- When did it take place?
- Why did it happen?
- How did it happen?
The problem with news shows today is the Why, where instead of simply reporting the actual facts of Why, they offer up manufactured speculative opinion of Why.
When a field reporter or an anchor gives their opinion on the story they are reporting, it's not news, it's commentary. If you ever hear "what this means is..." then it's not news, it's commentary. They're telling you what and how to think about the story. O'Reilly, Hannity, Fox and Friends, people actually think these are news programs, and what's worse, many people get the bulk of their news from shows like these.
There are today hours upon hours of televised air time on the cable networks dedicated to the Iowa Caucuses and the political process, only minutes of which contain the Five Ws. The rest is commentary, and it's hard to pick the needle of news our of the haystack of commentary.
In the meantime, people are awash with commentary, and are awash with it in a passive manner where they just sit back and take it all in the same way they watch propaganda commercials for Swiffers, Tide, and prescription medication. And because it's absorbed into the brain passively, they believe it, and they go out and buy Swiffers, Tide, and prescription medication, just like they buy into the political propaganda, absorbed passively, and believe it. There's a reason certain advertising techniques work, and it's the same reason "conversational news" works to manipulate the passive viewer.
Today, where news broadcasts are either almost entirely commentary, or are so interspersed with commentary that it's hard to discern fact from opinion, people are being manipulated on a large scale, with many of them even refusing to believe they are being manipulated. It's both scary and pathetic. Frankly, you're better of getting your news from Twitter. <snort>
