20/20
originally aired on ABC
20/20 (stylized as 2020) is an American television newsmagazine that has been broadcast on ABC since June 6, 1978. The program's name derives from the "20/20" measurement of visual acuity. The two-hour-long program has been a staple on Friday evenings (currently airing at 9:00 Eastern Time Zone) for much of the time since it moved to that timeslot from Thursdays in September 1987.
