I had a few spare minutes so I decided to watch a number of Chow Tips in succession. Probably watched about 25 and 95% of them were preceded by the same NCAA March Madness ad. I thought my head would explode if I sat through it one more time. I've never noticed this level of repetition before. I would assume the advertiser buys blocks of time or space but my feedback is that it can backfire, though I'm still going to watch the games and that site really is as awesome as the ad says (point is, however, I had been to that site before and might have been turned off to it if I hadn't). Aren't these ads randomized by some system?
