Exploring KBS Cool FM: South Korea's Premier Hot AC Radio Station
For music lovers in South Korea, few stations offer the nostalgic charm and high-energy entertainment found on KBS Cool FM.

The Evolution of a Radio Icon
The TBC Radio Era (1965–1980)
The roots of Cool FM trace back to June 1965 with the launch of the Tongyang Broadcasting Corporation (TBC), the former body of what is now JTBC. On June 27, 1965, Radio Seoul Broadcasting began broadcasting on 639 kHz. By 1966, the station was renamed TBC Radio and introduced an 89.1 MHz FM repeater. A major milestone occurred in 1970 when TBC Radio launched South Korea's very first Stereo FM broadcast.
This era came to an end on December 1, 1980, when TBC Radio was forced to merge into KBS following a special law enacted under the military authorities of President Chun Doo-hwan.
The KBS 2FM Era (1980–2003)
Following the merger, the station relaunched on December 25, 1980, as KBS 2FM. During this period, the format shifted toward Trot (a traditional Korean music genre) and popular music. To reach a wider audience, KBS utilized a "Cross-Broadcast" system, sharing selected shows nationwide through the KBS Local FM Network.
As the station grew, so did its availability. In 1988, it began partial 24-hour broadcasting, and by October 1, 1994, it transitioned to a full 24-hour broadcast schedule. Technical capabilities also improved significantly; in 1990, the transmission power was increased to 10 kW (TPO).
The Modern Cool FM Era (2003–Present)
On October 10, 2003, the station was officially rebranded as KBS Cool FM. This era has been defined by technological innovation and public engagement. In 2005, KBS opened its studios to the public, and by 2006, the station began visual radio (BORA) broadcasts, allowing listeners to watch programming via the internet. In 2010, the transmitter was moved from Mount Namsan to Mount Gwanaksan to optimize coverage.
