A tabloid talk show is a subgenre of the talk show genre which emphasizes controversial and sensationalistic topical subject matter. The subgenre achieved peak viewership during the late 20th century. 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. Tabloid talk shows have sometimes been described as the "freak shows" of the late 20th century, since most of their guests were outside the mainstream. The host invites a group of guests to discuss an emotional or provocative topic – ranging from marital infidelity to more outlandish topics – and the guests are encouraged to make public confessions and resolve their problems with on-camera "group therapy". Similar shows are popular throughout Europe.
Tabloid talk shows are sometimes described using the pejorative slang term "Trash TV", particularly when producers appear to purposely design their shows to create controversy or confrontation, as in the case of Geraldo (such as when a 1988 show featuring Ku Klux Klan and Neo-Nazi members, anti-racist people and Jewish activists led to an on-camera brawl) and The Jerry Springer Show, which focused on lurid – often between family members. Vicki Abt, Ph.D., professor of sociology and American studies, criticized tabloid TV shows, claiming that they have blurred the lines between normal and deviant behavior. The genre experienced a particular spike during the 1990s, when a large number of such shows were on the air, but which gradually gave way during the 2000s to a more universally appealing form of talk show.
