Most of the time I space out during commercials. Sometimes I remember the theme but don't remember what product they are for - take that: Madison Avenue.
There is a particular ad for FoxWoods that I am obsessed with (and drive rsc crazy by seeing it in slowmo, backing up, etc. and wishing we had HD so the details would be clearer). In this ad there is a couple who arrive - each carrying a suitcase and are greeted by the doorman/bellhop who says can I take those for you. They then proceed to unzip their body suits which include their faces and flip them to him and cavort off to dinner, dancing, and gambling. When they return wearing different clothes - presumably on another day, the doorhop asks if they want these back referring to their body suits which are sitting on the luggage cart and they so, "no, we're good" and walk off. Now during this conversation the woman is wearing a large red bag over her shoulder which she wasn't wearing when she came in (perhaps she bought it or it was packed). On the luggage cart are two suitcases but they don't look to be same as the ones they came in with even though their rumpled up body suits are on the cart. And in the final view 1-second view of the couple walking away (without their suitcases) the woman is not wearing her red shoulder bag.
Car ads usually have a SUV driving somewhere rugged that looks like it is on the moon or on top of a mountain or someplace else where no-one could drive. So I can always tell a car ad when it is coming on, but I never know what brand it is for.
Coors ads are particularly odd since the theme is either about how cold it is and/or how great the containers are (bottle turns blue when it cold enough, liners in cans, wide-mouth openings, etc.) and they never mention the flavor - probably because there isn't any.
I don't think I am the target audience of these ads.
On the other hand sometimes these ads are useful. There is an amusing Southwest ad that has a bunch of people sitting at a conference room table being bored by a presenter. At some point she switches to the next PowerPoint slide and says "now on slide 88 of 250". Yesterday when I went to an LCFD finance committee meeting (I am the treasurer) I described this as we started. At some point during the meeting when we had digressed (the meeting is informal and I had no PowerPoint slides but we did examine some spread sheets) as we did various times I was able to say: "and now back to slide 88 of 250"
