Fred Silverman, executive for daytime programming at CBS, was then looking for a show that would both revitalize his Saturday-morning line and please the watch groups. The result was The Archie Show, based on Bob Montana's teenage humor comic book Archie. Also successful were the musical numbers The Archies performed during each program (one of which, "Sugar, Sugar", was the most successful Billboard number-one hit of 1969). Eager to build upon this success, Silverman contacted producers William Hanna and Joseph Barbera about creating another show based on a teenage rock group, this time featuring teens who solved mysteries between gigs. Silverman envisioned the show as a cross between the popular I Love a Mystery radio serials of the 1940s and either the Archie characters or the popular early 1960s television series The Many Loves of Dobie Gillis.
