The band, created by Titi Soto, enjoyed huge success during the early 80's, particularly in Puerto Rico and Central America. A movie (Coneccion Caribe) was filmed and a tv show hosted weekly on Puerto Rico's WAPA-TV. Many songs, including Puerto Rico son Los Chicos and Terremoto became radio favorites, and memorabilia items like T-Shirts, school items, magazines, baseball hats and posters were mass produced.
Ultimately, Los Chicos went bankrupt in 1984. While it never achieved Menudo's level of popularity, it gave them a run for their money in Puerto Rico and many Latin American countries.
Los Chicos' most popular members were Chayanne (now an international super-star) and Tony.
In the aftermath of the success achieved by six former Menudos in a comeback nicknamed '\'El Reencuentro'', some former members of Los Chicos spoke about maing a comeback too. This never materialized, however.
