Formed around a cast of lovable teenage Puerto Ricans (each of whom was forced out once he reached the age of 16), Menudo were the first Latin group to gain success around the world. The initial lineup formed in 1977. They made a medium-sized splash in America during the mid-'80s -- though all of the original members had long since passed -- with the 1984 LP Reaching Out, which included English-language versions of their biggest hits. Though Menudo's brand of disposable synthesizer pop dated and faded quickly in America, the group continued to rule much of Central and South America, and ousted member Ricky Martin made a successful solo career. ~ John Bush
