I hate ads, but I'm struggling to understand how something being an ad disqualifies it from being art. Advertising is a creative human endeavor. Ads are designed to make you feel something, just like art.
The romantic ideal is that art is not about consumption, but the reality, both historically and currently, is that art objects are by and large made to be bought and sold. If you disqualify all works meant for consumption, you would have very little left that we currently recognize as art.
There are a long list of arts with adjectives in front of them. commercial art, applied art, fine art, etc...they aren't art just because you have co-opted art to mean only fine art. Also see:
Art and design exist ubiquitously in all things and all actions. It is the people without taste who pretend art or design is a separate activity from all other human endeavors. Perhaps a subset of "pure" or obvious art are works devoid of function except to be perceived.
"Art should comfort the disturbed and disturb the comfortable." - Cesar A. Cruz
