This paper examines the performance of radio host Kyle Sandilands, which is one of intended confrontation. However, the genre of radio to which his performance is associated is not talkback. It is chat-based programming, which relies on three tenets: orientation to the personal, use of wit, and risk of transgression. This paper examines the question: To what extent is Kyle Sandilands performance of authenticity oriented to the genre format? This paper argues that the overall success of Sandilands is supported by his mastery of the chat-based genre.
