What the thing is
Graffiti is writing or drawings made on a wall or other surface, usually without permission and within public view. Spray paint and markers are the main tools used for tagging, throw ups and pieces.
Where it came from
It began in the New York City subway system and Philadelphia in the early 1970s. Tags were the first form of stylised contemporary graffiti, starting with artists like TAKI 183 and Cornbread. Graffiti itself is far older than that. Examples survive from ancient Egypt, ancient Greece and the Roman Empire, and the oldest known written graffito, found on the Greek island of Astypalaia, is dated to around 500 BC.
What it gets right
It asserts presence without invitation. It uses speed, repetition and scale to turn infrastructure into a broadcast medium.
What it gets wrong
It is routinely mislabelled as street art. Murals are often permitted. Graffiti is not.
Why it matters now
It remains the most widespread, unmediated form of public text—visible, unsanctioned, and legally precarious—amid rising surveillance and privatisation of urban space.
Is it worth your time
Yes—if you want to understand how public space, permission and authorship collide. No—if you expect a coherent movement or unified aesthetic.
