The wheel series: How NBC rotated detective dramas to dominate 1970s television programming
In short: In 1971, NBC launched an innovative umbrella program that rotated multiple detective dramas within a single time slot. By cycling through different series each week, the network kept audiences guessing about which investigator would appear, turning a scheduling experiment into a major ratings success that lasted until 1977.
The concept of the wheel series originated from a 1966 production agreement between NBC and Universal Studios. The network ordered a multi-year run of feature-length dramatic anthologies, with Universal retaining international rights to release the productions as films. This collaboration aimed to provide high-quality content, utilizing top-tier actors and writers, while managing the logistical challenges of producing 90-to-120-minute episodes. The first series under this arrangement was The Name of the Game, followed by others like The Bold Ones.
The NBC Mystery Movie officially debuted in the 1971–1972 season, featuring a trio of detective dramas: McCloud, Columbo, and McMillan & Wife. The format proved highly successful, finishing at number 14 in the Nielsen ratings during its first year. The rotation was designed to keep viewers engaged, as the opening credits were specifically sequenced to reveal the night's featured detective. While the Sunday series thrived, NBC attempted to expand the format with The NBC Wednesday Mystery Movie, which included shows like Banacek and Cool Million, though this midweek iteration struggled to maintain ratings and was canceled by 1974.
By the late 1970s, the commercial broadcast landscape shifted. Situation comedies became more popular due to lower production costs and greater flexibility for syndication. The feature-length mystery anthologies were difficult to package for re-runs because they could not easily be edited for shorter time slots. Despite the eventual cancellation of the umbrella series in 1977, individual programs like Columbo and Quincy, M.E. continued to find success. The format was later revived by ABC in 1989, proving that the wheel concept remained a durable, if challenging, model for television storytelling.
