Graffiti in New York City has had a local, countrywide, and international influence. Originating in the "New York City Subway and spreading beyond it, it is regarded by the city's authorities as an act of "vandalism, while some view it as an "art form.
Modern graffiti began in "Philadelphia, in the 1960s. Shortly after the death of "Charlie Parker (nicknamed "Yardbird" or "Bird") in 1955, graffiti began appearing around New York with the words "Bird Lives" but it was not for about one and a half more decades that graffiti started to be noticeable in NYC. Around 1970-71 the center of graffiti culture shifted from Philadelphia to New York City, especially around "Washington Heights, where writers such as "TAKI 183 and "Tracy 168 started to gain media attention. Using a naming convention in which they would add their street number to their nickname, they "bombed" a train with their work, letting the subway take it throughout the city. Bubble lettering was popular among writers from "the Bronx, but was replaced with a new ""wildstyle", a term coined by "Tracy 168 and a legendary original Graffiti crew with over 500 members include "Blade, Cope 2, T Kid 170, Cap, Juice 177, and Dan Plasma. Graffiti tags started to grow in style and size. Notable names from that time include "DONDI, "Lady Pink, "Zephyr, "Julio 204, "STAY HIGH 149, "PHASE 2.
Graffiti writing was growing competitive and artists desired to see their names seen in all of the city. Around 1974 writers like Tracy 168, CLIFF 159 and BLADE ONE started to create works with more than just their names: they added illustrations, full of scenery and "cartoon characters, to their tags, laying the groundwork for the "mural-car. The standards from the early 70s continue to evolve, and the late 1970s and early 1980s saw new styles and ideas. As graffiti spread beyond "Washington Heights and "the Bronx, a graffiti movement was born. "Fab 5 Freddy (Friendly Freddie, Fred Brathwaite) was one of the most important graffiti figures of that era. He notes how differences in spray technique and letters between Upper Manhattan and Brooklyn began to merge in the late 70s: "out of that came 'Wild Style'." Fab 5 Freddy is often credited with helping to spread the influence of graffiti and "rap music beyond its early foundations in the Bronx, and making links in the mostly white downtown art and music scenes. It was around this time that the established art world started becoming receptive to the graffiti culture for the first time since Hugo Martinez's Razor Gallery in the early 1970s.
The growth of graffiti in New York City was helped by its "subway system, whose accessibility and interconnectedness facilitated the rise of a community of subway graffiti writers and muralists. It was also aided by the budgetary restraints on New York City, which limited its ability to remove graffiti and perform transit maintenance. Mayor "John Lindsay declared the first war on graffiti in 1972, but it would be a while before the city was able and willing to dedicate enough resources to that problem to start impacting the growing subculture.
As graffiti became associated with crime, many demanded that the government take a more serious stance towards it, particularly after the popularization of the "Fixing Broken Windows philosophy. By the 1980s, increased police surveillance and implementation of increased security measures (razor wire, guard dogs) combined with continuous efforts to clean it up led to the weakening of New York's graffiti subculture. As a result of subways being harder to paint, more writers went into the streets, which is now, along with commuter trains and box cars, the most prevalent form of writing. But the streets became more dangerous due to the burgeoning "crack epidemic, legislation was underway to make penalties for graffiti artists more severe, and restrictions on paint sale and display made obtaining materials difficult.
Many graffiti artists, however, chose to see the new problems as a challenge rather than a reason to quit. A downside to these challenges was that the artists became very territorial of good writing spots, and strength and unity in numbers ("gangs) became increasingly important. This was stated to be the end for the casual subway graffiti artists.
In 1984 "New York City Transit Authority (NYCTA) began a five-year program to eradicate graffiti. The years between 1985 and 1989 became known as the "diehard" era. A last shot for the graffiti artists of this time was in the form of subway cars destined for the "scrap yard. With the increased security, the culture had taken a step back. The previous elaborate "burners" on the outside of cars were now marred with simplistic marker tags which often soaked through the paint.
By mid-1986 the "Metropolitan Transportation Authority (MTA) and the NYCTA were winning their "war on graffiti," with the last graffitied train removed from service in 1989. As the population of artists lowered so did the violence associated with graffiti crews and "bombing." However, teenagers from inner London and other European cities with family and other links to New York City had by this time taken up some of the traditions of subway Graffiti and exported them home, although New York City writers like Brim, Bio, and Futura had themselves played a significant role in establishing such links when they visited London in the early-to-mid-80s and 'put up pieces' on or near the western ends of the "Metropolitan line, outside London.
Almost as significantly, just when subway graffiti was on the decline in New York City, some British teenagers who had spent time with family in "Queens and "the Bronx returned to London with a "mission" to americanize the "London Underground Limited (LUL) through painting New York City-style graffiti on trains. These small groups of London "train writers" (LUL writers) adopted many of the styles and lifestyles of their New York City forebears, painting graffiti train pieces and in general 'bombing' the system, but favoring only a few selected underground lines seen as most suitable for train graffiti. Although on a substantially smaller scale than what had existed in New York City, graffiti on "LUL rolling stock became seen as enough of a problem by the mid-1980s to provoke the British Transport Police to establish its own graffiti squad modeled directly on and in consultation with that of the MTA. At the same time, graffiti art on LUL trains generated some interest in the media and arts, leading to several art galleries putting on exhibitions of some of the art work (on canvass) of a few LUL writers as well as TV documentaries on London hip-hop culture like the BBC's 'Bad Meaning Good', which included a section featuring interviews with LUL writers and a few examples of their pieces.
The "Clean Train Movement, wherein the rolling stock was either cleaned or outright replaced, started in 1985, with the last graffiti-covered train out of service by 1989.  With subway trains being increasingly inaccessible, many graffiti artists had to resort to new ways to express themselves. Rooftops became the new billboards for some 80s-era writers. Some notable graffiti artists of this era were "VEN, KET, COPE 2, POEM, SANE, SMITH, and others. The current era in graffiti is characterized by a majority of graffiti artists moving from subway or train cars to "street galleries." Prior to the Clean Train Movement, the streets were largely left untouched not only in New York City, but in other major American cities as well. After the transit company began diligently cleaning their trains, graffiti burst onto the streets of America to an unexpecting and unappreciative public.
City officials elsewhere in the country smugly assumed that gang graffiti were a blight limited largely to the Big Apple [New York City]. The stylized smears born in the South Bronx have spread across the country, covering buildings, bridges and highways in every urban center. From Philadelphia to Santa Barbara, Calif., the annual costs of cleaning up after the underground artists are soaring into the billions.
The graffiti also spread to trains on "Rome Metro's "Line B, which ordered new trains in the 1990s that were quickly tagged with graffiti. The trains on Rome's metro are still heavily tagged to this day, partially due to the fact that graffiti still is rampant on the Metro's trains despite efforts to clean it. However, the Rome Metro's "Line A does not have graffiti on its trains because they have newer, more graffiti-resistant rolling stock, which is also being phased in on Line B.
Meanwhile, in New York in 1995, Mayor "Rudolph Giuliani set up the Anti-Graffiti Task Force, a multi-agency initiative to combat the problem of graffiti vandals in New York City. This began a crackdown on "quality-of-life crimes" throughout the city, and one of the largest anti-graffiti campaigns in U.S. history. That same year Title 10-117 of the New York Administrative Code banned the sale of aerosol spray-paint cans to children under 18. The law also requires that merchants who sell spray paint must either lock it in a case or display the cans behind a counter, out of reach of potential shoplifters. Violations of the city's anti-graffiti law carry fines of US$350 per incident. Local graffiti artist "Andrew Witten wrote a viewpoint opposing this law.
On January 1, 2006, in New York City, legislation created by Councilmember "Peter Vallone, Jr. attempted to raise the minimum age for possession of spray paint or permanent markers from 18 to 21. The law prompted outrage by fashion and media mogul "Marc Ecko who sued Mayor "Michael Bloomberg and Councilmember Vallone on behalf of art students and "legitimate" graffiti artists. On May 1, 2006, Judge George B. Daniels granted the plaintiffs' request for a preliminary injunction against the recent amendments to the anti-graffiti legislation, effectively prohibiting the "New York Police Department from enforcing the higher minimum age. A similar measure was proposed in "New Castle County, Delaware in April 2006 and passed into law as a county ordinance in May 2006.
At the same time, graffiti has begun to enter mainstream. Much controversy arose on whether graffiti should be considered an actual form of art. Since the 1980s, museums and art galleries started treating graffiti seriously. Many graffiti artists had taken to displaying their works in galleries and owning their own studios. This practice started in the early 1980s with artists such as "Jean-Michel Basquiat, who started out tagging locations with his signature SAMO (Same Old S***), and "Keith Haring, who was also able to take his art into studio spaces. In some cases, graffiti artists had achieved such elaborate graffiti (especially those done in memory of a deceased person) on storefront gates that shopkeepers have hesitated to cover them up. In the Bronx after the death of "rapper "Big Pun, several murals dedicated to his life done by BG183, Bio, Nicer "TATS CRU appeared virtually overnight; similar outpourings occurred after the deaths of "The Notorious B.I.G., "Tupac Shakur, "Big L, and "Jam Master Jay.
