1) The influence on TV on political process is unmistakable. In America the number of people who get their news through television rises steeply. In 1960 it was found out, that people who watched Kennedy on the TV had made a good impression of him and the ones who listened to the presidential campaign debates of Nixon on the radio had inclined toward Nixon. The Roper Organisation discovered in 1984, that 51% got their news trough television, 31% through newspapers and 18% through other sources.
2) TV news conveys 'a feeling of immediacy with a sense of being "on the spot" and involved in the action.'(l 12) and you could say that it connects 'timeliness with visual excitement'(l 11). Because of that it can create a sense of confidence. Another advantage of TV is that everybody is informed at the same time. For example 90% of the nation was informed within an hour of John F. Kennedy's assassination. It's maybe also positive that you only get the facts even if it is a very compressed story. It is handy that you get informed very quickly.
3) The two statements "The big problem is that TV news producers like pictures" (Neil Hickey) (l.22) and "The range of visual images...is surprisingly narrow."(Kidder) (l. 23) are, as I see it, a total contradiction. Because if TV news producers like pictures so much, why are there not many?
4) The meaning of "headline service" so that "context is lost" (l.28,30) is very easy to explain. On TV you just get the basic stuff, the facts, details are unimportant. And maybe because the details disappear, it's difficult for some people to understand the context from one headline to the other. Thus when you want to know a lot about something particular you maybe should better read a newspaper!
I think, the best way to escape of manipulation and to acquire a certain knowledge is to get your news from all the 3 media. ...
