Art galleries are institutions or forums to promote art appreciation in art buyers and a platform for artists to display their work. The term art gallery initially denoted a particular area or gallery in a museum to display paintings, sculptures, and illustrations. The popularity and success of this concept encouraged reserving rooms and later, private and public independent buildings exclusively for exhibitions, seminars, art teaching, and research programs.

Fame or notoriety of a gallery is dependent upon the artists showcased and, to a large extent, the connection with an art dealer. The partnership encourages benchmarks of excellence, as sincere dealers ensure maximum exposure for the gallery and artist.

A wider demand for art and artists encouraged the establishment of online galleries to help source and purchase paintings or sculptures from galleries and art dealers in different cities or countries. Art collectors or novices find this a convenient way to browse through paintings of different artists, depending on taste and setting. But there is nothing to compete with the artistic ambience of an uptown gallery showcasing traditional and exclusive artists or a downtown one selling contemporary or kitschy works of new and emerging artists.
