"Cash Cab" is spreading the wealth.

The Discovery Network show that turns a New York City cab ride into an instant game show is launching a spinoff version based in Chicago next spring. Comic Beth Melewski, a "Second City" cast member, will be behind the wheel.

The expansion comes after a triumphant year for "Cash Cab." The series, itself a remake of a British TV's similar game based in London, won its second Daytime Emmy award for best game show. Ben Bailey won his first Emmy as best host.
