From It's Bigger Than Hip Hop, a book by M.K. Asante, Jr.:
...The artivist (artist +activist) uses her artistic talents to fight and struggle against injustice and oppression—by any medium necessary. The artivist merges commitment to freedom and justice with the pen, the lens, the brush, the voice, the body, and the imagination. The artivist knows that to make an observation is to have an obligation.
