Furthermore, to find out why listeners like local cultural programs of each radio. This research on broadcast content on four cultural radios uses virtual ethnographic methods by collecting data, both offline and online. Researchers are involved in broadcasting activities on four cultural radios (offline) and listener interaction activities in the virtual world (online), namely Facebook and WhatsApp. This study conducted interviews with twelve informants representing radio management, local cultural figures, and loyal listeners. The results showed that each radio has excellent cultural programs with a solid appeal to maintain listener loyalty. The four cultural radios involve cultural experts in designing cultural programs.
