Abstract
A method of generating advertising revenue by securing an FM subcarrier frequency through an FM broadcasting station and distributing portable receivers to end users tailored to play the audio signals broadcast over the FM subcarrier frequency, on demand. Public service audio clips and advertising audio clips are broadcast to the portable receivers with the intention that a listener will be exposed to both the public service audio clip and the advertising audio clip during the period of the broadcast. The public service audio clips and advertising audio clips are broadcast in a continuous loop and are coded with start and stop signals to indicate the beginning and end of the broadcast. Through this method, an individual requesting the broadcast will hear a signal loop of the audio, starting with the detection of the start signal and ending when the detection of the stop signal.
