 The structure of a single host introducing a series of acts became a popular television style and can be seen consistently in the development of television, from "The Milton Berle Show" in 1948 to "Late Night With David Letterman" in the 1980s.The multi-act format had renewed success in shows such as "Your Show of Shows" with Sid Caesar and "The Ed Sullivan Show".Today, performers such as Bill Irwin, a MacArthur Fellow and Tony Award-winning actor, are frequently lauded as "New Vaudevillians".
