Perhaps, Craig, it is a matter of semantics.
The ability to pack the TV bands was the direct result of moving to digital
modulation, where there are (in theory anyway - I hear you Doug Lung...)
fewer taboo channels, and more tolerance of interference before it becomes
noticeable.
This does (again, in theory) open up more white space for other uses, even
as the overall television band is reduced.

The expanded access to airwaves offers a solution. The unused bands of
spectrum were generated by the conversion of television signals from
analog to digital. Because digital transmission uses a smaller slice of
spectrum, more "white space" was freed up around each broadcast signal. It
is those white spaces that the F.C.C. is now seeking to put to use.
I thought someone might comment on this misleading statement from the
story I posted yesterday.
Clearly the author does not have a clue about the history of the "White
Spaces," or what effect the DTV transition had (will have) on their use.
