Besides providing information, advertising also supports the entertainment industry, including television and radio. It may be annoying to sit through commercials during your favorite TV show, but the advertising have paid for its production. This, in turn, pays the TV crew for their work. Even public broadcasting has supporters. The companies' names appear at the beginning or end of the showa. Without their sopport, there would be more hours of pledge drives asking you, the consumer, for more money. Many presenters, such as newsreaders, get their starts from writing or appearing in commercials or print advertisements. Is's a way for them to get both experience and exposure.
