With the rebellion of the artist against established art came the need for a more versatile and utilitarian medium. Some say that medium was “ready-made." Ready-made is an art term used to describe a mass-produced item, such as a tire, pen, or bar of soap. These common items, when incorporated into art, supposedly attach a greater value to aid item. Art created with ready-made pieces are at times controversial, and their authenticity is sometimes questioned.

Many artists have used ready-made media to create art, most notably those in the Abstract and Pop Art movements. Some famous artists who gained their status using ready-made media are Jean-Michel Basquiat (everything he created), Marcel Duchamp (Fountain), and of course, the infamous Andy Warhol (100 Campbell's Soup Cans).
