Dotto
Dotto is an 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 premiered on January 6, 1958 as part of CBS' daytime lineup. Due to its popularity, an accompanying weekly nighttime edition was launched on July 1, 1958 and, in a change of pace, was carried by CBS' competitor NBC on Tuesday nights. However, at the height of both shows' popularity, Dotto was revealed to have been fixed by its producer and the news resulted in both series being cancelled during the week of August 11–15, 1958.
