 [No title]
CD Radio had proposed that satellite DARS system operators be permitted temporarily to occupy frequency assignments other than their own, provided that their transmissions can be reconfigured to return to and thereafter use only their own frequency assignment upon launch of the satellite operated by the licensee assigned to the temporary frequency.
CD Radio asserts that receiver inter-operability is in the clear economic interests of all satellite DARS providers and it expects that its receiver will be fully tunable in the sense that the consumer can select the service provider of their choice.
Terrestrial broadcast and satellite DARS services are at different stages of development, however, and we do not intend to add delay to the progress of the satellite service with further regulatory intervention by requiring that receivers be tunable to terrestrial broadcast signals.

About the same time that satellite radio broadcasters were starting their long regulatory journey to implementation, terrestrial radio broadcasters were facing up to the fact that sooner or later, they, too, must chart a digital course.
Digital radio receivers with memory allow for the downloading and storing of audio files that can be selected on demand, or for capturing specific news, traffic, and other programs that can be retrieved later, providing the audio equivalent of a VCR (or the newly popular hard-disk personal video recorders) for radio listeners.
Terrestrial broadcasters will be the first to boast that their trump card in all of this maneuvering can be summed up in one word: localism.

These include introduction of a new radio service to the public, a national distribution of radio programming to all areas, including underserved and unserved areas and population groups, the creation of jobs and the promotion of technological development in the satellite and receiver industries, and the improvement of U.S. competitiveness in the international economy.
Third, national advertising revenue amounts to only 18% of terrestrial radio advertising revenue and is on average less important for small-market stations than for large-market stations.
The value of radio station purchases in 1996 was 315% higher than in 1995 and radio station values as a multiple of cash flow also rose sharply.

Radio will be the primary media vehicle in the campaign, but other media, including Print and the Internet-based will also be used.
What I like about satellite radio is the fact that you don't have to be in one location to hear your favorite show, terrestrial radio doesn't have that capability.

 Howstuffworks "How Radio Works"
Even though radio waves are invisible and completely undetectable to humans, they have totally changed society.
Whether we are talking about a cell phone, a baby monitor, a cordless phone or any one of the thousands of other wireless technologies, all of them use radio waves to communicate.
Things like communication and navigation satellites would be impossible without radio waves, as would modern aviation -- an airplane depends on a dozen different radio systems.

Add to the volume of listeners the fact that terrestrial radio has fewer stations thus a more focused and consolidated audience than any of the new radio challengers.
With billions of dollars in market capitalization, radio is not going to roll over and play dead and one of the latest new technologies that could possibly inject new digital life into a creatively boring media like FM radio comes from iBiquity.
The technology has support from some of the big radio groups which is a good step in the right direction however they will need major support from the big consumer electronics manufacturers and more importantly from automakers.

 SignOnSanDiego.com > News > Technology -- Terrestrial digital radio makes commercial debut
Unlike satellite radio, a subscription service that also uses digital signals, digital radio represents a technological upgrade of the free service offered by traditional "terrestrial" broadcasters.
The new high-definition radios will have to compete with the nation's two satellite radio services, Sirius and XM, which now claim nearly 1.5 million subscribers and offer largely commercial-free broadcasts of music, sports and talk throughout the country.
Struble and other digital radio masterminds said they chose Iowa to unveil the commercial product because Cedar Rapids' KZIA-FM was sending out digital broadcasts; because Iowa is home to radio pioneer Arthur Collins; and because of Iowa's precinct caucuses that kick off the presidential nominating season.

 Digital radio has arrived
I had hoped that the terrestrial form would beat the satellite form to a service date, but this was not to be.
Analog terrestrial radio can sound good, and FM service with few interference problems is accepted as a quality sound source.
It is my hope that Sirius and XM will demonstrate to terrestrial radio stations that listeners like a true variety, and therefore entice local stations to broaden their playlists and look beyond the safe choices.

 The Big Picture: How Did Terrestrial Radio Lose its Audience ?
It was during this time of consolidation when radio’s leadership took their eye off the ball, looking to economies of scale to cut costs and boost profits.
With these added channels, satellite radio is able to niche-program while terrestrial radio is trying to cast a big net around an audience that is increasingly difficult to capture.
Radio networks remind me of Detroit in the 70s - busy rearranging financial deckchairs and cost-cutting while viewing the end product as a milk-cow or something to be taken for granted and coasting on past reputation.

The Times of London quoted Dan Wertheimer, a radio astronomer from the University of California at Berkeley and the project's chief scientist, as saying researchers are not jumping up and down, but we are continuing to observe it.

The prediction is that year-over-year radio advertising will increase by 4.3% or more and the research from the radio Adlab all points to a rosy future for this “doomed” medium.

Industry insiders are excited about high-definition radio, which marries analog and digital signals and sends out a hybrid data stream.

In HD radio, the analog signal travels over 96.7, and as many as eight additional digital signals can be sent using the 96.6- and 96.8-MHz bands.
