Protagonistas
"Protagonistas..." aka Protagonistas de Novela, Protagonistas de la Música, Protagonistas de la Fama is a Spanish language Reality Television franchise. It's very popular in Spanish speaking countries in Latin America and also airs in Latin communities in the United States.
The game format is pretty similar to Big Brother or Operación Triunfo (Star Academy) where a group of anonymous people compete in an isolated house to win a contract with a record company or the TV channel.
