Dotto was a 1958 American television game show that was a combination of a general knowledge quiz and the children's game connect the dots. Jack Narz served as the program's host, with Colgate-Palmolive as its presenting sponsor. Dotto rose to become the highest-rated daytime program in television history, as of 1958.Dotto replaced Strike it Rich in CBS's 11:30 am daytime time slot on January 6, 1958. In a rare instance of two networks programming the same show, a weekly nighttime edition was launched on July 1, 1958 on CBS's competitor NBC on Tuesday nights in their 9:00 p.m. slot. At the height of both shows' popularity, Dotto was abruptly cancelled without public explanation over the weekend of August 16, 1958. Soon after, Dotto was publicly revealed to have been fixed by its producer, tarnishing the show's reputation and setting the stage for legal and political investigation of the fixing of 1950s quiz shows.
