Street art is visual art created in public places, usually outside of traditional art venues. The term became popular during the graffiti (涂鸦）art boom of the early 1980s. The average person on the street would associate street art with run-down urban centers and New York’s graffiti explosion of the 1970s and 1980s. During that period, graffiti artists often painted subways, benches, and other urban surfaces. But artists who choose the streets as their gallery often do so because they prefer to communicate directly with the public at large and be free from the confinement of the formal art world. Therefore, most major cities now have what is called a“wall of fame”一a public space where street artists come to paint，compete，and connect with other artists.
Located near Dubai International Airport, Dubai Festival City, for example, was host to street art from 2007 to 2011. At an event sponsored by Montana, a popular spray paint brand, a wall was designated as a canvas for international artists to work on. After the event, officials allowed the wall to remain, and creative art workers would get together there every weekend. Since then, Dubai has made a name for itself in the art world. It has a respected annual art fair called Art Dubai, which, having celebrated its thirteenth year in March 2019，is widely regarded as one of the highlights of the Middle East’s art calendar.
The street art scene in Dubai operates with the approval of the authorities. Planned works on buildings or murals painted on wood panels are beginning to pop up on blank walls and at art events all over the city, thanks largely to the support of art galleries and institutions. Corporate collaborations, though frowned (皱眉）upon by some artists, are also helping to make street art more visible in Dubai.
