In 1941, Lyle Goodhue and William Sullivan developed the aerosol spray can, initially designed to dispense insecticide for soldiers during World War II. This portable canister technology was later adapted for commercial products like paints and hairsprays, revolutionizing packaging and consumer goods. The aerosol spray can became a ubiquitous item, influencing both industry and daily life.

The introduction of the aerosol spray can in 1941 enabled the creation of street graffiti art and concrete poetry, altering the physical execution and public distribution of urban underground writing. Poets like David Antin and the Beat poets utilized this medium to challenge traditional forms and reach new audiences.
