Hellenic Public Radio – COSMOS FM (HPR) broadcasts under the aegis of the Greek American Educational Public Information System, Inc. (GAEPIS) – a not-for-profit media, educational organization. GAEPIS is dedicated to the preservation and promotion of Hellenic heritage in the United States via the media of mass communication.

GAEPIS was founded in 1987 to meet the needs of Hellenic Americans, serving the Hellenic-American community in all its diversity.

By providing quality coverage of issues and informative and educational programs in both English and Greek, GAEPIS seeks to address the needs of recent immigrants from Greece and Cyprus, Americans of Hellenic descent and Philhellenes.​

GAEPIS identified the medium of public radio as the most effective way to realize its goals.

Radio was chosen because it is widely and inexpensively accessed, and because it can meet the audience’s demand for the most up-to-date reporting of events.​Public radio is essential because it offers independence from advertisers or politicians who may otherwise attempt to influence or restrict the coverage of issues that concern our community.

This public channel exists solely to serve the interests of the community as a whole.

Hellenic Public Radio – COSMOS FM is the only daily, bilingual non-commercial Greek radio program in the New York Metropolitan Area.

HPR has over 5,000 supporting members and reaches over 200,000 Hellenic and non-Hellenic listeners each week.​
