Bill Cullen hosted both the daytime and nighttime versions of the show. For two seasons (1959–1961), the nighttime version was eighth in the prime-time Nielsen ratings, making it the most-watched game show on television at the time. Cullen's easygoing personality was cited as a key part of the show's success. The show gained popularity during the years following the quiz show scandal, becoming the most-watched prime-time game show from 1959 to 1961. The show was a precursor to the current and best-known version of the show, premiering in 1972 on CBS and in syndication.
