美国早期电视：深夜脱口秀

　　In the early years of US television, a new form of entertainment was created: the late night talk show. Steve Allen was the first of his kind and he was noted for its wacky comedy and willingness to engage in crazy stunts. It was also a showcase for African-American performers such as Cab Calloway and Count Basie. He was succeeded in 1957 by Jack Paar, a skilled interviewer who got his start in radio and brought the art of conversation to the small screen. Johnny Carson followed as the next and undoubtedly most popular host of the show. He agreed somewhat reluctantly and became a TV staple for the next 30 years. His success led to many others trying their hand at the format, some successfully, including Merv Griffin, Joey Bishop and Dick Cavett.
