Prime time is the highest-profile television daypart, from 7:00 or 8:00 p.m. to 10:00 or 11:00 p.m., depending on the network and time zone. The highest rated programs on television often air during prime time, and almost all scripted programming (except soap operas, game shows, and more recently, sketch comedy shows) air during the prime time slots. Occasionally, especially during the 1980s and in the 2000s, programs that were "daytime oriented" sometimes enter the prime time daypart, such as the popular nighttime soap opera "Dallas" and the game show "Who Wants to Be a Millionaire". Usually the main reason for the high profile of prime time television is due to the fact that many people who come home from work and school tend to watch television rather than engage in any other activity.
