Local TV stations in the United States normally broadcast local news three to four times a day on average: commonly airing at 4:30, 5:00, 5:30, or 6:00 a.m.; noon; 5:00 and 6:00 p.m. in the early evening; and 10:00 or 11:00 p.m. Some stations carry morning newscasts at 4:00, 7:00, 8:00, or 9:00 a.m., midday newscasts at 11:00 or 11:30 a.m., late afternoon newscasts at 4:00 or 4:30 p.m., or early evening newscasts at 5:30 or 6:30 p.m. Many Fox affiliates, affiliates of minor networks (such as The CW and MyNetworkTV), and independent stations air newscasts in the final hour of primetime (i.e., 10:00 p.m. in the Eastern and Pacific time zones or 9:00 p.m. in the Mountain and Central time zones in the U.S.). Stations that produce local newscasts typically broadcast as little as one to as much over twelve hours of local news on weekdays and as little as one hour to as much as seven hours on weekends; news programming on weekends are typically limited to morning and evening newscasts as the variable scheduling of network sports programming (if a station is affiliated with a network with a sports division) usually prevents most stations from carrying midday newscasts (however a few stations located in the Eastern and Pacific time zones do produce weekend midday newscasts).
