"Show business," often shortened to "showbiz" since around 1945, is a vernacular term encompassing all facets of the entertainment industry. Originating in print by 1850, it traditionally covers both the creative talent—such as artists, writers, and performers—and the essential business roles of managers, producers, and distributors. Throughout the 20th century, the term was widely used and has evolved to include modern elements like the fashion industry and intellectual property rights.

Economically, the global media and entertainment market is immense, valued at an estimated $2.14 trillion in 2020. The U.S. entertainment industry alone constitutes the largest market, contributing over one-third of that total. This dynamic sector spans a vast array of subsectors, including film, music, broadcasting, video games, sports, and amusement parks, demonstrating its broad cultural and economic reach worldwide.
