You can't possibly pay attention to every ad you are subjected to. You can always try to avoid ads' invasiveness and irrelevence by muting the volume, looking elsewhere, fast-forwarding or finding ad-free media.
“Just think of those people who don’t look at the ads when they ride the bus or the subway — if you are reading a book instead, you’re stealing! Drive on major roads without reading all the billboards? Theft! Theft, I say!. Throw out your junk mail? Why, you criminal! Junk mail subsidizes the rest of your mail; to not read it is stealing or something! Take the brand label off of a pair of pants? Didn’t read the beer ad on the coaster in the bar? You evil freeloader! Stay where you are and wait for the police to arrive.”

"Your contract with the network when you get the show is you’re going to watch the spots. Otherwise you couldn’t get the show on an ad-supported basis. Any time you skip a commercial or watch the button you’re actually stealing the programming.’ ... I guess there’s a certain amount of tolerance for going to the bathroom. But if you formalize it and you create a device that skips certain second increments, you’ve got that only for one reason, unless you go to the bathroom for 30 seconds. They’ve done that just to make it easy for someone to skip a commercial.”
