Street art originated in New York City in the 1970s as artists displayed work in subway stations and on city streets. It grew alongside hip hop culture and became more widely accepted. Street art is defined as unsanctioned artwork created in public spaces rather than galleries. It has influenced and expanded the traditional art world while also having cultural and social impacts through provocative works addressing current issues. Technology has also allowed new forms of street art like stencils and stickers to proliferate globally and cross cultural boundaries.
