These are the late-night schedules for the three television networks during the 1969–70 season. All times are Eastern and Pacific.
NET is not included, as member television stations had local flexibility over most of their schedules, and broadcast times for network shows might have varied. ABC and CBS are not included on the weekend schedules because those networks did not offer late-night programs of any kind on the weekend.
Talk/Variety shows are highlighted in yellow, Local News & Programs are highlighted in white.
