Contemporary art gallery. A generally a for-profit, privately owned businesses that sells artworks. There are also galleries run by art collectives, not-for-profit organizations, and local or national governments. Galleries run by artists are sometimes known as Artist Run Initiatives, and may be temporary or otherwise different from the traditional gallery format. Galleries are distinct from art museums. Other than size, the biggest difference between a gallery and a museum seems to be that galleries sell their work, often for a profit. However there are many galleries that do not sell artwork, so there is a considerable grey area.
Many contemporary art galleries specialize in avant-garde art, and others specialize in anything from old-masters to local artists to art-objects, crafts, etc. Contemporary art galleries are often found clustered together in urban centers such as the Chelsea district of New York or Wynwood, in the old warehouse district in Miami.
