Four in One (TV series)

Four in One is the umbrella title for a wheel series broadcast in the United States on the NBC television network as part of its 1970-71 schedule in the Wednesday 10 PM Eastern time slot.

Four in One consisted of six episodes of each of four dramatic series: McCloud, San Francisco International Airport, Night Gallery and The Psychiatrist. All six episodes of each program were run in order; then all were rerun interspersed with each other with a different series being shown each week.

After the season, McCloud had proven sufficiently popular to be included as an element in a new wheel-format series, NBC Mystery Movie, while Night Gallery was picked up as a stand-alone series. The other two elements, San Francisco International Airport and The Psychiatrist, were cancelled.
