Joel Brinkley's "Defining Vision" book presented the whole
ATSC/HD/digital transition as a 1980's ploy by broadcasters to put off
land mobile while grabbing more spectrum rights. Some day we may
actually know whether he was right.
Things were certainly delayed for awhile. They probably will be delayed
for a much longer.
Can anybody explain the spectrum rights James Snyder below claims were
acquired "under the radar"?
