An artist is a person, a group of people, or a registered organization or company that devotes themselves to making art. Art can be anything, that others find beautiful, and that enriches the cultural values of a society: Music, movies, paintings, literature, and games are all art forms of various kinds. But this page focuses on games, music, and movies, because those are the art forms that are under attack from piracy.
To give a few examples:
Id Software (makers of Doom 3)
Twenty Century Fox & Lukas Films (Makers of Star Wars movies)
Yes, these are all artists.
Piracy KILLS artists
