Digital Radio FCC Approves Plan for Digital Radio - "Some digital car stereos will have small screens, displaying pictures of the artist whose song is playing, news or advertising. Others will allow listeners to choose to hear reports on stocks, sports, weather and traffic. The digital broadcasts will be free, unlike the subscriber services offered by Sirius Satellite Radio and XM Satellite Radio Holdings, which beam music and talk to radios from satellites. The iBiquity technology allows broadcasters to use their existing airwaves and simultaneously send digital and analog signals. Listeners won't have to buy a new radio to continue listening to their favorite stations, but will if they want better sound and other options."
