National Radio Television Foundation

The EIRT was the fourth state broadcasting organisation of Greece and the first state TV operator in Greece. The first broadcasting organisation of Greece was the Radio Broadcast Service (Υπηρεσία Ραδιοφωνικής Εκπομπής, Ypiresía Radiofonikís Ekpompís; ΥΡΕ/YRE), which was replaced by Radio Station Athens (Ραδιοφωνικός Σταθμός Αθηνών, Radiofonikós Stathmós Athinón; ΡΣΑ/RSA), founded by the 4th of August Regime of Ioannis Metaxas in 1938.

The second operator was Radio Broadcasting Anonymous Company (Ανώνυμη Εταιρεία Ραδιοφωνικών Εκπομπών, Anónymi Etaireía Radiofonikón Ekpompón; ΑΕΡΕ/AERE), again with Radio Station Athens, which was established during the Occupation. In 1945, the National Radio Foundation (Εθνικό Ίδρυμα Ραδιοφωνίας, Ethnikó Ídryma Radiofonías; ΕΙΡ/EIR) was founded by the Constituent Act 54/1945 "establishing the National Radio Foundation," whereby it became the owner of all the property of the former AERE.
