One Day (part) at a time

I was perusing my favorite sports sites and blogs this AM, when I came across a page with a Pizza Hut Ad on it...you know the one they are pushing now...the pizza with the mozzarella sticks as crust or something (USA! USA!)

I am not a Pizza Hut eater...I live in NYC...but it struck me how many impressions are wasted by not properly day-parting buys (it was 7:30 A.M when i saw the ad). Certainly a pizza ad is going to result in better metrics around lunch or dinner time.

Sure this creates a problem on the sell side, as you need a more effective yield management system to properly charge for the ads...but I bet that we could figure it out

Besides food ads...what other ads should be more concerned with day-parting?
