Is the term "award winning" meaningless?

I’ve seen this twice today, and both times it bothered me.

Companies will advertise “our award-winning new coverage” or “buy our award-winning frozen biscuits” or “stay at our award-winning hotel”.

To be meaningful or believable, should the advertiser tell you:
a) what the award was
b) when it was awarded
c) what were the qualifications to win the award
d) who or what organization made the award
?

Otherwise, it seems like “award-winning” is just another hyperbolic claim.

Is “award winning” as meaningless as “clinically tested”?
