One of the most crucial media forms

One of the most crucial media forms in the 20th century was broadcast. From my perspective, it will develop unremittingly, though people listen to it not frequently. However, it occupies an important position on a daily basis. For instance, during the commuting time, or traffic jam, when an individual drives a car, he tends to open the car radio that reports road conditions, weather forecasts, and musics so as to kill time. For the old people who are unfamiliar with high-tech electronic equipment, such as mobile phone or PC, they are able to listen to the radio to know about life events. Moreover, as the acceleration of life and work pace, time is amount to money, so a large proportion of time is spent on work, and only a small part could be used for rest or entertainment. And more and more music applications emerge. They actually promote the development of broadcast. Thereafter, with the development of internet, broadcast will get increasingly better.
