This is probably quite a silly question, but it's been bothering me slightly ever since I visited. It was probably because I was not long enough in one city, plus the large number of channels on offer (something like 70 or 80 in the hotel in Chicago?), but I never did get the hang of a typical TV schedule, always ending up surfing semi-randonly at night.
First I'll tell you how Aussie TV scheduling works.
In Sydney and in fact across most of the country, we have four commercial stations, one government-paid-but-run-independant ([link|http://www.abc.net.au/tv/|ABC]), and one about halfway ([link|http://www.sbs.com.au/|SBS]). I can ignore one commercial station at this point ([link|http://www.tvs.org.au|TVS]) because they're very new, they don't have a lot of coverage and they don't publish their schedule where everyone else does.
Two of the other three commercial stations ([link|http://www.seven.com.au/|Seven] and [link|http://www.ninemsn.com.au|Nine]) have a gameshow or something light at 5pm, then another at 5:30, a half-hour news at 6pm, a current affairs program at 6:30, a soap or a gameshow at 7pm, an hour's episode of some series, such as a drama, at 7:30 (or two half-hours shows, 7:30 and 8) and either a movie at 8:30 or a more hour-long shows (8:30, 9:30, 10:30...), usually followed by a late news bulletin at a variable time. The third commercial station ([link|http://www.ten.com.au/|Ten]) starts a little differently, with an hour's news at 5, a soap at 6, a comedy at 6:30, usually a reality-TV show at 7, and then as above. This pattern has been in place for longer than I've been watching TV, so we're very used to working around the half-hours for things, and catching a movie at 8:30. Even Ten did this for a long time before putting their news at 5 because they couldn't compete at 6. Heck, the ABC and SBS work around that on-the-half-hour thing, too. Even though ABC's news is at 7pm, it has a current affairs program at 7:30, something half-an-hour at 8, and hour-long stuff usually at 8:30 and 9:30 or so (the ABC only runs ads for its own programs, so what might be an hour program with ads, will finish in 45 minutes on the ABC).
US TV doesn't seem to work that way. I just took a gander at some of the big US network website and their schedules. I noticed things are oriented around the o'clock. Hour-long shows start at 8, 9 and 10. There's always a news bulletin at 11pm. CBS also has news at 5pm, 6pm and 7pm (there's that much news?)! The Aussie late night news is never at a reliable time. It took me a long time to grasp why the phrase "<such and such normal/impossible thing occured>. Film at 11." was humourous.
I know this is probably one of those "why is he bothering" posts. But I'm curious. Like I said above, we're long accustomed to certain types of patterns in TV schedules in Australia. The 8:30pm movie is one of the most well-known ones. I'm curious as what the US ones are!
