The deal with iBiquity will put its in-band on-channel technology  usually known by its acronym IBOC  into 95% of Clear Channel Radio's top 100 markets within three years. IBOC significantly improves the sound quality of both AM and FM broadcasts while adding features possible only with digital technology, such as displaying text or rich media directly on the face plate of the radio.
