I own a DVR, hence I don't watch commercials.
It seems like the vast majority of commercials specifically aimed towards men could be condensed into a single phrase: Trucks, breasts, beef, bacon.
Have you considered that these two phenomena are probably linked? You think the ad agencies aren't designing ads with DVRs in mind?
I'm a TiVo user - and it doesn't allow you to completely skip commercials. You fast-forward, getting a series of images from the commercials for a bit, before you get to the program again.
Any competent advertiser is going to try to get those images to make you want to stop and watch the commercial. If you're a guy with the remote in hand, what images are apt to get you to stop the fast-forward?
