HD radios not selling - HD shills to the rescue !

Your graph DOES NOT show that HD radios are not selling. They have
nothing to do with sales - only google web hits. Do you even bother
to read the links before posting?

A meaningful graph would compare the number of listeners to free
broadcast (AM & FM) to XM, Sirius and HD radio. Guess what - the
curves for the last three would be all but flattened by the curve for
free broadcast (AM&FM).
