Bootlegging refers to the illegal production, distribution, or sale of goods, most commonly alcohol. This practice became particularly prominent in the United States during the Prohibition era (1920-1933), when the manufacture and sale of alcoholic beverages were banned. Bootleggers often smuggled alcohol from other countries or produced it secretly to meet the demand of consumers. In addition to alcohol, bootlegging can also apply to the illegal trade of other goods, such as drugs or cigarettes. The term has evolved to include the unauthorized copying and distribution of music and movies, highlighting the ongoing challenges of copyright infringement in the digital age.
