It also diversified by purchasing 80 percent of JuJu Media, the operator of the Spanish-English Web site LaMusica.com, which offered Latin music, entertainment, news, and culture.

Later that year, at the insistence of Alarcón Jr., SBS launched KZAB-FM (La Sabrosa 93.5), targeting the Central American population in Los Angeles.
