Las Vegas, NV — National Association of Broadcasters Show — April 19, 2004 — iBiquity Digital Corporation, the sole developer of HD Radio technology, today unveiled a comprehensive list of more than 300 licensed stations that have initiated or soon will initiate HD Radio broadcasts throughout the U.S. In addition, the company also announced that San Jose’s KEMR-FM 105.7, owned by Univision, last week became the 100th station nationwide to successfully commence full-time HD Radio broadcasts.

Visitors to www.HD-Radio.com can now search for stations across more than one hundred markets that are at the forefront in bringing crystal-clear digital sound quality and next-generation data services to their community. This new feature is part of iBiquity’s strategy of partnering with local stations and retailers to promote the availability of HD Radio technology within each market and follows the recent appointment of several executives to spearhead these efforts.

“Stations spanning from Boston to Los Angeles and beyond, including Alaska and Puerto Rico, are today bringing HD Radio’s revolutionary technology to communities large and small,” said Robert Struble, president and chief executive officer of iBiquity Digital Corporation. “With the ongoing success that stations are enjoying in their transition to HD Radio broadcasting, we’re now delighted to welcome the millions of radio listeners across the nation to the party. With radio serving first and foremost as a cherished local medium, stations’ ability to promote the introduction of HD Radio broadcasts directly to listeners within their community coupled with the growing retail availability of HD Radio receivers paves the way for radio’s newest golden era.”

The experience of Ohio State University’s WOSU-FM is typical of the excitement greeting the introduction of HD Radio broadcasts within many communities. The station unveiled its enhanced broadcasts on April 5, 2004 with Congresswoman Deborah Pryce pushing the button that officially launched radio’s digital era in Columbus, Ohio. In addition to its on-air promotions, the station is also launching a print campaign entitled, “The best seat in the house just got better!” that highlights their leadership position as the first station in central Ohio to broadcast using HD Radio technology.

With the availability of a constantly updated, online resource tracking the nationwide rollout of HD Radio, consumers across the country can now follow its success within their markets as more and more stations flip the switch to this next-generation of radio.
