How long is their newscast on a normal night? I'm with you on this one; they should have just thrown in the towel and called it a night.
During past World Series (and/or baseball playoffs leading up to them), our FOX affiliate has moved their 9:00 p.m. news over to one of their sister stations. They probably didn't have enough of a "heads up" to do that this time.
60 minutes for the 10 PM news. Maybe the news director Steve Schwaid was insistent on having news on, following the race.
We typically have an hour and a half of late local news on Fox 17, from 9:00 to 10:30, which to me seems excessive, but I'm guessing that they get to "have their cake and eat it, too," airing the first late evening newscast, and then going on to compete against all the others.
