Street art is a very popular form of art that is spreading quickly all over the world. You can find it on buildings, sidewalks, street signs and trash cans(垃圾桶) from Tokyo to Paris, from Moscow to Cape Town. Street art has become a global culture and even art museums and galleries(画廊) are collecting the works of street artists.

Street art started out very secretly because it was criminal to paint public and private things without permission(允许).
People often have different opinions about street art. Some think it is a crime and others think it is a very beautiful new form of culture.
Art experts say that the street art movement began in New York in the 1960s. Young adults painted words and other images on walls and trains. This colorful style of writing became known as graffiti(涂鸦). Graffiti art showed that young people wanted to be against society. They didn’t want to accept rules and travelled around cities to create paintings that everyone could see. In many cases, they had trouble with the police and the local government.
One well-known New York street artist is Swoon. She cuts paper images of people and puts them on walls or sets them up on sidewalks. Swoon didn’t start her career as a street artist. She studied art, but as time went on, got bored with the works she saw in museums and galleries. People in New York enjoy Swoon’s strong and imaginative style. Some museums have already bought some of her works.
Advertising companies also use street art in their ads because it gives people the feelings of youth and energy.
In Today’s world the Internet has a big influence on street art. Artists can show their pictures to the audience all over the world. Many city residents, however, say that seeing a picture on the Internet is never as good as seeing it live.
The street art movement lives with the energy and life of a big city.
