Art21 is a nonprofit organization that seeks to promote the work of contemporary artists. While the organization is best known for their PBS documentary series Art in the Twenty First Century, Art21 has also produced a number of digital series. These include Extended Play, a series that features footage of artists at work, and Artist to Artist, a series that features multiple artists in conversation with each other. Visitors can check out these series in the Watch section of the website, where visitors will also find a number of Playlists of video clips that center on a specific theme. For example, the Take Action playlist features clips about artists who explore contemporary political and social issues through their work. Visitors will also find an Art21 Artist Index that provides biographical information about select contemporary artists, as well as a Magazine that reports on art projects from around the world.
