<bot>: The phrase “Let’s make a deal” can be traced back to the early 1900’s, when it was a common phrase said when two parties were negotiating a deal. It quickly became popular in the 1920s, when it was adopted as a catch phrase by one of the earliest game shows in the U.S., titled "Let's Make a Deal", hosted by Monty Hall.
