The HD radio Brand came from HD television. Now HD television is actually high defintion. HD radio in many cases will be low def. Multicasting can lower audio quality. In radio the codec is IBOC, and owned by Ibiquity exclusively. So they have some control over branding you could say....
Excellent Blog on Stories Related To HD

iBiquity Twists Its Tubes"
"Any simple WHOIS domain-name search turns up the obvious: iBiquity owns HDRadio.com. Administrative and technical contacts point straight back to the corporate HQ. My question is, why all the disclaimage? And are you really that clueless, iBiquity? Are you effectively denying the validity/credibility of your consumer-marketing claims?.. Hiding behind a trademark-disclaimer - that HDRadio.com is 'managed' by the HD Radio Alliance - which is, for all intents and purposes, iBiquity (though that particular domain is registered to Clear Channel) - does not cut the mustard."

"But the best comes at the expense of consultant and paid iBiquity HD Radio shill Fred Jacobs... Here’s a tale of two research studies, one of which vanished into thin air – or at least was thought to. You see, it started when a new 41-question survey about HD Radio from Jacobs for iBiquity was mentioned in a Radio-Info.com forum on October 31. Almost immediately, the original survey vanished and was replaced by this sanitized 16-question version... So who pulled the original HD Radio survey – and why?"

"Regardless of a country’s licensing regime with regard to access to the airwaves, the wholly proprietary nature of iBiquity’s HD Radio system trumps public authority... a conflict with iBiquity could mean the station’s effective silencing. This is especially important for noncommercial and community radio stations... The average estimated cost per station for the hardware necessary to put an HD Radio signal on the air is about $100,000. This does not include a one-time licensing fee to use the HD Radio software, which ranges from $10,000 to $25,000 per station, and only covers the basic use of the HD Radio mode."

"Instead of honest competition, they decided they would make the government compel all broadcasters to convert to digital on the existing AM and FM bands. To accomplish this, the NAB plans to double the amount of space on the dial that a station uses, thus jamming the signals of weaker stations next to them on the dial... Grassroots defenders of independent radio have found proof that a new airwaves regulatory plan will jam and eventually destroy the signals of small community, religious, and college radio stations... In addition to eliminating competition, the true financial motive of the digital conversion is the creation of a new largely subscription system, called 'IBOC-DAB'... The real plan is to make their money from selling that remaining space to send wireless data, not for a lively, competitive radio signal."

"Perhaps it is because it is the American Public that has been paying a large portion of the development costs for HD radio? Yup, that is you and I. An FCC filing from North Carolina’s Public Radio Stations cites: Just a few weeks ago, the House Appropriations Committee approved an additional $40 million to assist public radio stations’ transition to HD radio technology.”

HD radio boosters like to say that HD Radio is to AM/FM as HDTV is to regular television. The reality is somewhat murkier, but we'll get to that.
The company iBiquity is the primary one behind HD Radio. The idea is to digitize formerly analog FM and AM broadcasts, which would theoretically make them less susceptible to interference and other problems. iBiquity claims that HD Radio makes AM sound as good as FM and FM sound as good as CD audio.
HD Radio also allows broadcasters to piggyback multiple channels (up to three) on the same band, so you could tune into FM 99.7 and get either rock, jazz, or all-Elmo-all-the-time, depending on which sideband you selected. And unlike satellite radio (a clear inspiration for HD Radio), HD is free, but it's also local. You won't get an HD signal any farther away than you will a regular AM or FM broadcast.
Surprisingly, HD Radio has many broadcasters using it nationally. About 1,000 stations, as a matter of fact. You probably never noticed this because they're all still broadcasting analog radio too. The HD broadcast can ride side by side with the original.
So, HD Radio sounds great on paper....cont'd
