A talk show is a television programming, radio programming or Podcast genre structured around the act of spontaneous conversation. A talk show is distinguished from other television programs by certain common attributes. In a talk show, one person discusses various topics put forth by a talk show host. This discussion can be in the form of an interview or a simple conversation about important social, political or religious issues and events. The personality of the host shapes the tone and style of the show. A common feature or unwritten rule of talk shows is to be based on "fresh talk", which is talk that is spontaneous or has the appearance of spontaneity.

A tabloid talk show is a subgenre of the talk show genre that emphasizes controversial and sensationalistic topical subject matter. The subgenre originated in the United States and achieved peak viewership from the mid-1980s through the end of the 1990s. Airing mostly during the day and distributed mostly through television syndication, tabloid talk shows originated in the 1960s and early 1970s with series hosted by Joe Pyne, Les Crane, and Phil Donahue; the format was popularized by personal confession-filled The Oprah Winfrey Show, which debuted nationally in 1986. The format has since been emulated outside the United States, with the United Kingdom, Latin America and the Philippines all having popular shows that fit the format.
