The work of radio hosts and TV hosts is similar to each other in many ways. First, both radio hosts and TV hosts must be fluent in languages. Second, they are all supposed to have a wide knowledge of culture, history, geography and so on. In addition, they must give completely correct information. 　　However, there are also some differences between them.
