Сальса
Salsa music became the dominant genre of tropical music in the 1970s. Fania Records was credited for popularizing salsa music, with acts such as Rubén Blades, Héctor Lavoe, and Celia Cruz expanding the audience. In the late 1970s, an influx of balladeers from Spain such as Julio Iglesias, Camilo Sesto, and Raphael established their presence on the music charts both in Latin America and the US Latin market. In 1972, OTI Festival was established by the Organización de Telecomunicaciones de Iberoamérica as a songwriting contest to connect the Ibero-American countries (Latin America, Spain, and Portugal) together. Ramiro Burr of "Billboard" noted that the contest was considered to be the "largest and most prestigious songwriting festival in the Latin music world".
