20/20 is an American television newsmagazine that has been broadcast on ABC since June 6, 1978. Created by ABC News executive Roone Arledge, the show was designed similarly to CBS's 60 Minutes but focuses more on human interest stories than international and political subjects. The program's name derives from the "20/20" measurement of visual acuity. The hour-long program has been a staple on Friday evenings for much of the time since it moved to that timeslot from Thursdays in September 1987, though special editions of the program occasionally air on other nights.

Biography is a documentary television series. It was originally a half-hour filmed series produced for CBS by David Wolper from 1961 to 1964 and hosted by Mike Wallace. The A&E Network later re-ran it and has produced new episodes since 1987. The older version featured historical figures such as Helen Keller and Mark Twain, or long-dead entertainment figures such as Will Rogers or John Barrymore. The A&E series has placed the emphasis on such people as Marilyn Monroe, Elvis Presley, Plácido Domingo, Freddie Mercury, Jacqueline Kennedy Onassis, Eric Clapton, Pope John Paul II, Gene Tierney, Selena, Diego Rivera, Mao Zedong and Queen Elizabeth II, and fictional characters like The Phantom, Superman, Hamlet, Betty Boop, and Santa Claus. The program ended up profiling enough figures that in 1999, A&E spun it off into an entire network, The Biography Channel.
