Explanation of program host's nouns

The Journalism Manual has a relatively complete definition, that is, in radio and television, people who appear to host various programs for the audience or listeners are called program hosts. The host is not a performer, nor is he different from the broadcaster of news dissemination and articles. A host is a person who directly faces the audience or audience with his own identity and personality. The host is in a dominant position in the program, whose main duty is to connect all parts of a program in series, but also to directly spread information or answer questions or introduce knowledge or provide entertainment to the audience, and always talk to the audience or audience in the first person "I" tone. This is a relatively complete and authoritative expression of the concept of program host in China.
