A talk show (American and Australian English) or chat show (British) is a television or radio program where one person or group of people come together to discuss various topics put forth by a talk show host. Sometimes, talk shows feature a panel of guests, usually consisting of a group of people who are learned or who have great experience in relation to whatever issue is being discussed on the show for that episode. Other times, a single guest discusses their work or area of expertise with a host or co-hosts. A call-in show takes live phonecalls from callers listening at home, in their cars, etc.
