The term "black market" originated in the 1930s, particularly during the Great Depression, when illegal trading and the sale of goods occurred outside regulated channels. It refers to the trade of goods and services that are illegal or conducted in violation of government regulations. The "black" in "black market" signifies its illicit nature, contrasting with the "white market," which refers to legal and regulated commerce. Over time, it has come to encompass a wide range of illegal activities, including the trafficking of drugs, weapons, and counterfeit goods.
