Pop art was a rebellion against abstract expressionism. By 1955, abstract expressionism had become the official 'serious' American art — huge, expensive, expressive, intentionally hard to read. Pop artists said: what if we made art from the stuff people actually look at? Cereal boxes. TV. Magazines. Soup cans.
The work was usually mechanical-looking on purpose: silkscreens, perfect dots, flat color. The idea was that mass-produced imagery had become the real visual language of the late 20th century. If you wanted to talk about America in 1962, you couldn’t do it without Coca-Cola and Marilyn Monroe.
Pop opened the door for everything from contemporary advertising to street art to design culture. Without Warhol, no graphic-design Instagram aesthetic. Without Basquiat, no contemporary art market for Black artists at the scale we have today.
