iBiquity Digital Corporation is a privately held company with operations in Columbia, Maryland, Auburn Hills, Michigan, and Piscataway, New Jersey. The roots of the Company stretch back to 1991 when CBS, Gannett, and Westinghouse formed USA Digital Radio (USADR) to explore opportunities for digital AM and FM broadcasting. Following years of research and testing, USADR developed the In-Band On-Channel (IBOC) method of broadcasting which enables digital signals to travel the airwaves alongside traditional analog signals. IBOC remains the underlying principle behind today’s HD Radio technology.
By 1998, USADR had made such progress with the IBOC technology that it was spun out as a separate company, backed by investment from 13 of the nation’s leading radio broadcasters. iBiquity Digital was subsequently formed in 2000 with the merger of USADR and Lucent Digital Radio. The Company's investors include 15 of the nation's top radio broadcasters, including Clear Channel and CBS Radio; leading financial institutions, such as Grotech Capital Group, J.P. Morgan Partners, New Venture Partners, FirstMark Capital; and strategic partners Ford Motor Company, Harris, Texas Instruments and Visteon.
