The Mambo Machine is the longest running salsa show in New York City. The program was founded in 1971 by José "Cheo" Díaz, who didn't retire from hosting until thirty years later. Although the show began as one featuring mainly Mambo and Latin jazz -- Monday and Wednesday night's "Música en Nueva York" already featured Salsa -- the program presently plays a wide spectrum of Afro-Latin rhythms, combining new and old into an exciting, danceable mix.
