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). From the 1940s to the 1960s, broadcast television stations typically provided local news programs only one to two times each evening for 15 minutes (the normal length for many locally produced programs at the time); usually these programs aired as supplements to network-supplied evening news programs or leadouts for primetime programming. Reports featured on local and national television newscasts during this time were generally provided via film or still photography; eventually, videotape began to be used to provide live coverage of news events. The 1950s also saw the first use of airborne newsgathering; most notably, in 1958, Los Angeles television station KTLA began operating the "Telecopter", a helicopter equipped for newsgathering use that was the most advanced airborne television broadcast device of its time. The modern-day coverage of major breaking news events came to fruition following the assassination of John F. Kennedy on November 22, 1963; the news of Kennedy's death was first announced by Eddie Barker, the news director at KRLD-TV (now KDFW) in Dallas, who passed along word from an official at Parkland Hospital; Barker's scoop appeared live simultaneously on CBS and ABC as a result of a local press pool arrangement. Many local and national news organizations such as Dallas station WFAA-TV and CBS News provided
