Most advertising is wasted on me. If I remain in my seat while the next 10 minutes is filled with inane crapola, 20 ads for 20 products or services that I either already know about, don’t use, or don’t want, I have my brain trained to wander off and process other things during commercial breaks. As often as not, I’m up and away for those few minutes, getting something to drink or nibble on, or making proper disposal of the consumables from previous breaks. There are exceptions — commercials that are so well done or so clever that they command attention.
