Graffiti was used primarily by political activists to make statements and street gangs to mark territory. It wasn't till the late 1960s that writing's current identity started to form.The history of the underground art movement known by many names, most commonly termed graffiti begins in Philadelphia, Pennsylvania during the mid to late '60s and is rooted in bombing. The writers who are credited with the first conscious bombing effort are CORNBREAD and COOL EARL. They wrote their names all over the city gaining attention from the community and local press. It is unclear whether this concept made its way to New York City via deliberate efforts or if was a spontaneous occurrence.
Shortly after CORNBREAD, the Washington Heights section of Manhattan was giving birth to writers. In 1971 The New York Times published an article on one of these writers. TAKI 183 was the alias of a kid from Washington Heights. TAKI was the nick name for his given name Demetrius and 183 was the number of the street where he lived. He was employed as a foot messenger, so he was on the subway frequently and took advantage of it, doing motion tags. The appearance of this unusual name and numeral sparked public curiosity prompting the Times article. He was by no means the first writer or even the first king. He was however the first to be recognized outside the newly formed subculture. Most widely credited as being one of the first writers of significance is JULIO 204. FRANK 207 and JOE 136 were also early writers.
On the streets of Brooklyn a movement was growing as well. Scores of writers were active. FRIENDLY FREDDIE was an early Brooklyn writer to gain fame. The subway system proved to be a line of communication and a unifying element for all these separate movements. People in all the five boroughs became aware of each others efforts. This established the foundation of interborough competition.
Writing started moving from the streets to the subways and quickly became competitive. At this point writing consisted of mostly tags and the goal was to have as many as possible. Writers would ride the trains hitting as many subway cars as possible. It wasn't long before writers discovered that in a train yard or lay up they could hit many more subway cars in much less time and with less chance of getting caught. The concept and method of bombing had been established.
