Entertainment
Above all, talk shows posses the ability to amuse and entertain viewers in a wide variety of ways. Their format allows them to shift gears and present unique or unusual forms of entertainment in ways other shows cannot.
Education
Talk shows are an excellent format for discussing topics that viewers might not otherwise be exposed to. For example, zoologist Joan Embry's appearances on The Tonight Show often served to educate people about biology and conversation.
Popularity
The popularity of talk shows allows them to deliver messages to millions of households. While critics blanch at such influence, it has the ability to galvanize people towards positive ends.
