the phrase "breaking news"

The phrase "breaking news", can be construed as another form of semiotics. For me personally, every time i hear "breaking news" on television, i find myself glued to what is going on the whole time newscasters are explaining what's going on. I feel like society has trained us to pay attention to certain things in life, although not all breaking news is even news worthy. Take for example some sports talk radio shows, sometimes they will announce there is breaking news, then say something that is merely insignificant just to get the listeners attention. They know that people will pay more attention, by turning up the radio, but i believe this is just a tactic to attract more listeners. I think it is very interesting how our brains are trained to be more aware of certain words we hear in society.
