Los 40 Principales
Los 40 Principales is a chain of Contemporary Hit Radio stations in multiple Central and South American countries as well as Spain. "Los 40" began in Madrid in 1966 as a Top-40 chart show broadcast on Radio Madrid and later on Cadena SER stations. In 1979, 40 Principales expanded from an 8 hour show to its own network of stations dedicated to the Top-40 chart. They became an independent network in 1987.
