Prime time
On weekends, non-scripted programming such as comedy series, talent shows, reality shows and current affairs shows air in prime time. For the minor networks, prime time consists of American television series on weekdays, with encores of those shows on weekends. Prime time originally started earlier at around 19:00, but the evening newscasts were lengthened to 90 minutes and now start at 18:30, instead of the original one-hour newscast that starts at 18:00.
