What they can't find, I'm sure, is a person who KNOWS they have it. HD is in so many new products now, that it's frankly impossible that "nobody in Dallas has it". Check that. In a few months, there won't be a market in America, whether there are local HD stations or not, that don't have LOTS of the radios out there. Buy an inexpensive car radio, a Home Theater receiver, a docking unit for your Ipod (yes, there are models with HD!), a new car of certain brands (with more to come), a quality table radio, an executive shelf system, or one of many other products, from hundreds of distributors, including as far as I can tell ALL of the major-national consumer electronics products, and YOU'VE GOT HD! Silly proposition, (that "nobody has it) actually. Not so silly six months ago. Now, simply not possible, unless people in Dallas also don't have the above products.
I'll bet if the question was asked a different way, rather than "you don't have an HD radio, do you?" ask "HEY, you've got one of those great new HD radios, don't you?" the polling of exactly the same people would reveal completely different results. No, that's not wishful thinking. ANY pollster knows that it's all in HOW you ask the question! "Could you see yourself voting for that nice John Edwards?" vs. "You wouldn't vote for that John Edwards after you found out about his illegitimate love-child, could you?"
The only way to measure sales is to MEASURE SALES! There are two ways to "measure" Wal Mart's sales. One is to ask Wal Mart shoppers "did you buy this? Did you buy that?" as you go through the entire list of products they sell. The other is to check sales receipts AND ACTUALLY MEASURE WHAT WAS SOLD!
Particularly when it comes to technology, Americans have NO FREAKIN' IDEA WHAT THEY WANT! I'd wager that if you asked my wife "Do you have an upconverting DVD player in your home?" and "Can you play HD-DVDs at home now?" Her answer to the first would be "no", and to the second would be "yes". And BOTH ANSWERS WOULD BE WRONG!
