Street art began in the 1960s with graffiti related to jazz musician Charlie Parker in Philadelphia. Graffiti spread to New York in the 1970s and was pioneered by artists like TAKI 183. There are various reasons why people engage in graffiti, street art, and vandalism, ranging from expressing themselves artistically to gaining social acceptance to making political statements. While graffiti can beautify empty spaces and spread messages, it is also expensive to remove and can decrease property values if not properly regulated. Famous street artists like Banksy, Shepard Fairey, and Space Invader use the medium to comment on social and political issues, but their work is sometimes illegal and causes property damage.
