One of the first and most influential TV shows about hip-hop, Yo! MTV Raps debuted in August 1988 and continued until 1999, meanwhile hosting virtually every popular rapper of the time. And now, in commemoration, VH1 has created an entire documentary, “Yo! The Story of Yo! MTV Raps,” about the program, complete with highlights from some of the show’s most memorable and oft-YouTube’d moments as well as interviews with hosts Fab 5 Freddy, Ed Lover, and (the other) Doctor Dre. Fortunately, in case you missed the Rock Doc’s premiere, you’re now able to watch the entire 41-minute documentary on your own time.
