This is a programming question as old as TV. Cable channels provide flexibility we didn't have decades ago. That's part of the reason why national political conventions have largely disappeared from netwok coverage. But not everybody has cable/satellite TV. I've spent most of the afternoon bouncing back and forth between Fox and CNN. Frankly, I have no idea how much coverage the networks gave this event. It used to be suggested that for major breaking events coverage would rotate among the networks. The JFK assassination would be on NBC, for instance, while the other networks continued with their regular programming. The obivous weakness here is that while there would be a few folks who would watch "The Gong Show" during the presidential funeral, most would not. Plus, in the old days, networks were very proud of their news divisions, which were run by and populated with professionals. And network newsrooms would be in open rebellion if they were kept from reporting on major stories.
I'm not trying to pick a fight either, but you need to clarify your statement that your "interest in Canadian boys" is related to their wardrobe.
