Back in the days when the TV bulletin was fifteen to twenty minutes long once a night the news was just that - news. A newsreader would read out the headlines either accompanied by a picture of the related person/incident or a short film without commentary.
The nearest we would get to opinion would be a raised eyebrow or an inflection in the voice of the newsreader, but with the rise of 24 hour rolling news channels TV news reporting has changed radically.
One of the most disturbing changes - in my opinion - has been the rise of the talking head; a person who may or may not be employed by the news broadcaster, but is promoted by that organisation as an "expert" on a subject.
Now virtually every item of news includes the appearance of a talking head to explain what the news means - but this is almost invariably based purely on their own personal opinion or (if they are indeed employed by that broadcaster) the opinion of their bosses.
I have two problems with this. First of all, it doesn't allow much room for the viewer to form their own opinion. Although many will do so anyway, there is a huge number of people who will accept what that talking head says just because they are supposed to be an expert and they are appearing on a well regarded news channel which they trust.
My second problem is that it is not news broadcasting, but opinion forming which I believe should be kept out of television news reporting. Essentially, it is a form of propaganda which is insidious and damaging.
