"Concentration" was NBC's last black and white show, making
the switch to color in November 1966. "Everybody's Talking,"
which I maintain was the last b&w show on a commercial network,
debuted on ABC February 6, 1967; Two other b&w shows came after
"Everybody's Talking" and left before it: "Dateline: Hollywood" (April
3-September 29) and "The Family Game" (Wesley Hyatt lists this as
airing from June 19-December 29, but it aired before "Everybody's
Talking" on ABC's daytime schedule). I have some doubts that "The
Family Game" lasted until December 29; I remember being at my
grandparents' on December 27 and seeing a rerun of "The Donna
Reed Show" at 10:30 AM, the show's timeslot until Dick Cavett took
over in March 1968.
