Illegal broadcasting refers to the transmission of radio or television signals without the necessary licenses or permissions from regulatory authorities. This can include unlicensed radio stations that operate without following government regulations, which can lead to interference with licensed broadcasts and pose safety risks. Such activities are often pursued for profit or to share content that may not comply with legal standards. Authorities, like the Federal Communications Commission (FCC) in the United States, actively monitor and take action against illegal broadcasting to protect the integrity of the airwaves and ensure fair competition among licensed broadcasters.
