The government made 16 BILLION dollars on those "free" airwaves.
Just FYI.
I can't quite decide what you're trying to get at with this statement. This is a good thing... Right?
Those airwaves were free to both the broadcaster and the viewer to view free TV. Those frequencies were simply shifted to a different range and are still free (actually they were shifted to the UHF band which were already part of the "free" spectrum). The new digital broadcasts are much more efficient in regards to bandwidth and in comparison the analog signals are very wasteful. Nothing has changed in regards to free broadcasting.
This move freed up the VHF band that was being used for something else. That frequency sprectrum was sold for other uses which will in turn charge customers for its use. If companies are going to charge for the use of the spectrum then they certainly sould have to pay for it.
In the end there's just as much free broadcasting as there ever was (more actually since the bandwidth each station gets allows for sub-channels) and we're able to accomidate the much needed demand for other spectrum needs while making 16 BILLION dollars in the effort.
