When Jackson Pollock created many of his famous works, the United States was already at the forefront of the kinetic and popular art movements. The novel styles and methods he used to create his most famous pieces earned him the spot in the 1950s as the unchallenged leader of kinetic painters, his work was associated with Action painting coined by art critic Harold Rosenberg in the 1950s. Pollock had an unfettered desire to animate every aspect of his paintings. Pollock repeatedly said to himself, "I am in every painting". He used tools that most painters would never use, such as sticks, trowels, and knives. He thought of the shapes he created as being "beautiful, erratic objects".
