La 100

La 100 is an FM radio station created in 1987, after the purchase of Radio Mitre and FM 5 Estrellas by Grupo Clarín. Since then, it belongs to Grupo Clarín and has always had the same owners. It features a wide network of radio repeaters across the country with over 80 radio affiliates.

Its current programming includes two popular TV hosts in the two morning programs. Even though the programs focus on entertainment, music and general information, their large audience and the profiles of the radio’s main hosts make its news agenda one of the most relevant today.
