The history of graffiti can be traced back to cave paintings and can be considered among the first true marks ever made. The modern day inception probably came much much later in the late forties with the introduction of Kilroy. Kilroy made his mark on bombs he inspected by writing "Kilroy Was here". These bombs could be likened to the trains of New York in the way that they traveled great distances and were seen by many. Many G.I.'s in Europe would write "Kilroy was here" on walls as they took back cities from the Germans. Graffiti as we know it today probably got it's start in the 60's as social protest was getting it's foothold in America. The peace movement as well as the Black Panther movement both gave rise to various forms of vandalism. The true version of what we have ingrained in our heads as graffiti came from kids in the boroughs of New York. In the 1970's kids discovered that "tagging" the trains in the yards at night meant that their message or more likely their name could be seen by people all over the city, state, and even the country. This moving canvas led to a renaissance in the art form. Today the graffiti movement is still very much alive and has seen a leaning towards protest and the fight against commercialism and war with artists like Banksy and Ron English. Many older artists have seen validation as their once outlawed art has become more accepted by the mainstream.
