For all those loves of trivia, random people on New York streets, and Ben Bailey, I have some bad news. Cash Cab, the trivia game show that all happens in the back of a NYC taxi cab, has been cancelled. Link.
It's been 6 seasons and over 200 episodes for the show so by no means is it a failure. Just a strange decision by Discovery who I can only assume will take the cash for producing Cash Cab and put it into a show where guys steal things from elderly folks and sell them in pawn shops while they tow away random cars on the street.
Seems like a shame to me because you don't see too many trivia based game shows on anymore and Cash Cab certainly had an interesting concept.
