low-power FM

Low-power FM (LPFM) refers to radio stations that broadcast at low power, typically serving local communities. These stations are licensed by regulatory bodies like the Federal Communications Commission (FCC) in the United States and often broadcast at 100 watts or less, primarily reaching rural or small towns.1

Historically, unlicensed or "pirate" radio stations have existed, ranging from hobbyist operations to more elaborate undertakings that skirted regulations. The concept of microbroadcasting, where very low-power stations broadcasted to specific neighborhoods, gained traction in response to industry consolidation. Organizations like the Prometheus Radio Project have supported microbroadcasters in transitioning to licensed status, with efforts like the Local Community Radio Act in 2010 making it easier for noncommercial LPFM broadcasters to obtain licenses.2

FM radio, in general, has seen significant growth, offering more channels and program variety. In the United States, FM radio became the fastest-growing segment of the broadcast business during the 1960s, especially after the FCC approved standards for stereophonic sound and limited program simulcasting by co-owned AM and FM stations. Internationally, radio technology, due to its low cost and accessibility, provides opportunities for public media access, especially in regions like Latin America, Africa, and South Asia.31
