What are the advantages and disadvantages of broadcasting in spreading information?

Compared with other media, the advantage of broadcasting lies in its low material basis, that is, it can receive audio. The production cost is also low, the communication is easy, the use is flexible and the privacy is good. However, the gradual decline of broadcasting in today's era is due to its obvious weaknesses. Specifically, compared with integrated multimedia, its content is very simple and not rich enough, that is, it only has audio signals. This is unacceptable to many people, mainly because of the rapid development of modern natural technology, the conditions required for comprehensive media are greatly reduced, and the cost is also decreasing. Its flexibility is also greatly improved, and the information it receives is also greatly increased. Obviously, only audio signals can no longer meet the needs. Its advantages are gradually losing, so the market is gradually shrinking. But it is still a reliable media, it will not die out, and people always pay attention to it.
