Cash Cab s a game show where unsuspecting passengers enter a taxi in New York City and are quizzed on general knowledge questions to win money as they reach their destination. The show originally aired on the Discovery Channel.
The show's title seems to be influenced by the Monotype Grotesque Black font, designed by Frank Hinman Pierpont, based on the Ideal and William Thorowgood's 1832 "Grotesque" typefaces. Additional information on this font can be found here.
