What it is

Four amateurs broadcast the opera Parsifal from the Teatro Coliseo with a transmitter of their own and began regular programming as Radio Argentina. It is regarded as one of the first radio broadcasts open to the public.

World priority is disputed: KDKA of Pittsburgh started on 2 November 1920; there were earlier broadcasts in Detroit (8MK, August 1920) and in the Netherlands (1919). The Buenos Aires one is the first in Latin America with continuous programming.
