The First Social Network: In rural Argentina residents send messages w AM radio

In rural Argentina's remote Patagonian region, isolated pastoralists like gaucho Jorge Elías Pereyra rely on AM radio broadcasts called "Mensajes al Poblador Rural" to receive personal messages from family and the outside world, since they lack internet or cellphone service. Major radio stations throughout Argentina air these brief personal communications several times daily, allowing residents scattered across thousands of miles to stay connected through messages delivered by phone, WhatsApp, or hand-written notes.
