There’s no doubt at all. I must have the date confused with something else, probably the approval date. According to the Ibiquity site, the first station to broadcast commercially was on January 7, 2003.
“iBiquity Digital and its partners will formally debut commercial HD Radio products during a media conference at the International Consumer Electronics Show to be held on Wednesday, January 7, 2004 at 2:00 p.m. at Booth #4619 in the Las Vegas Convention Center’s North Hall. HD Radio products and demonstrations will be available at the booth through the show’s conclusion on Sunday, January 11.”
DTS is excited to announce it has entered into a definitive agreement to acquire iBiquity Digital Corporation, the developer of digital HD Radio technology for AM/FM audio and data broadcasting for approximately $172 million.
It will be interesting to see if DTS finds the magic to grow the technology.
