The History of Rock & Roll is an American radio documentary on rock and roll music, originally syndicated in 1969. One of the lengthiest documentaries of any medium (48 hours in the 1969 version, 52 hours each for the 1978 and 1981 versions). The History of Rock & Roll is a definitive history of the Rock and Roll genre, stretching from the early 1950s to its day. The "rockumentary," as producers Bill Drake and Gene Chenault called it, features hundreds of interviews and comments from numerous rock artists and people involved with rock and roll.
Notable features introduced in the 1978 edition of this documentary include the "chart sweep," featuring a montage of #1 songs and notable hits from a given year or artist, a "time sweep" for each one-hour segment providing a montage of the major hits for each year or individual artist, and closing with a special climactic time sweep featuring a montage of every #1 hit from 1955 to the year of the latest version.
While the documentary focuses on Rock & Roll and its variants, some songs and artists from other genres are also represented as they also became major hits on stations that primarily played Rock & Roll.
