Tom show is a general term for any play or musical based (often only loosely) on the 1852 novel Uncle Tom's Cabin by Harriet Beecher Stowe. The novel attempts to depict the harsh reality of slavery. Due to the weak copyright laws at the time, a number of unauthorized plays based on the novel were staged for decades, many of them mocking the novel's strong characters and social message, and leading to the pejorative term "Uncle Tom".
