The Federal Communications Commission has selected the IBOC system from iBiquity, marketed as "HD Radio" for digital audio broadcasting in the MF and VHF bands. AM and FM stations may if they wish begin interim transmissions immediately subject to an announced notification procedure. However, IBOC is not permitted for MF at night-time owing to the potential for skywave interference. FM IBOC is approved for both daytime and nighttime broadcasting. During the interim period, the same programme content will be broadcast on both the analogue and digital components. In its announcement, the FCC noted that although the proposed approach requiring new spectrum in TV Channel 6 was no longer under consideration, it was not categorically ruling out such consideration in the future. Should new spectrum be identified, both IBOC and non-IBOC approaches may then be considered. For satellite radio broadcasting, various mutually-incompatible systems are in operation. There is more information on the website digicomparison.

The Bay Area was the location of a technically successful trial of Eureka 147 DAB in 1996. This is believed to have been the only time that DAB has been broadcast in the United States, although reception of Canadian DAB was possible in Detroit, Michigan, via transmissions from Windsor, Ontario, until the ensemble ceased in 2006.
