SER, a privately owned company headquartered in Spain, operates as a Broadcast Media Production and Distribution entity. Founded in 1924, it employs approximately 1,950 individuals. The company, also known as La Cadena SER (the SER Network), functions as a Spanish radio network, with its operations providing radio services that reported a regular listenership of 4,139,000 in 2018. The acronym SER stands for Sociedad Española de Radiodifusión (Spanish Broadcasting Company).
Cadena SER Navarra is set to host the tenth edition of its SER Navarra Awards in Baluarte on January 20, 2026, where it will recognize the work and careers of individuals, companies, and institutions across various fields within the Autonomous Community. This follows an incident on January 18, 2026, when Cadena SER published an unverified AI-generated image of a train crash in Spain, which reportedly originated from Google's Nano Banana Pro image AI and displayed the Gemini logo. Earlier, on January 12, 2026, Lolo Viejo surprised Aimar Bretos with an AI-created song titled 'Hora 25,' which specifically referenced the broadcaster with the lyrics 'Hora 25 on the faithful broadcaster Cadena SER.'
