Page "Eastern Time Zone" Paragraph 34

Most cable television and national broadcast networks advertise airing times in Eastern time.

National broadcast networks ( ABC, CBS, The CW, Fox Network, NBC ) generally have two primary feeds, an eastern feed for Eastern and Central time zones, and a western feed for the Pacific Time Zone.

The prime time is set on Eastern and Pacific at 8: 00 p. m., with the Central time zone stations receiving the eastern feed at 7: 00 p. m. local time.

Mountain Time Zone stations receive a separate feed at 7: 00 p. m. local time.

As Arizona does not observe daylight saving time, during the summer months, it has its own feed at 7: 00 p. m. local time.

Cable channels with a separate western feed ( such as HBO, whose western feed is called " HBOW ") generally air the same programming as the eastern feed delayed by three hours.

Other cable networks such as the Discovery family of networks repeat their prime time programming three hours later ; this allows for the same show to be advertised as airing at " 8: 00 p. m. E / P " ( that is, " 8: 00 p. m. Eastern and Pacific time ").

Networks specializing in the airing of sports events, such as ESPN, advertise all of their programming in Eastern and Pacific, incorporating the 3-hour time difference ( as in " 8: 00 p. m. Eastern / 5: 00 p. m. Pacific ") and leaving viewers in the remaining time zones to calculate start time in their own areas.
