Documentary has undergone a marked revival in recent art, following a long period in which it was a denigrated and unfashionable practice. This has in part been led by the exhibition of photographic and video work on political issues at 'Documenta' and numerous biennials and, since the turn of the century, issues of injustice, violence and trauma in increasing zones of conflict. Aesthetically, documentary is now one of the most prominent modes of art-making, in part assisted by the linked transformation and recuperation of photography and video by the gallery and museum world. Unsurprisingly, this development, along with the close attention paid to photojournalism and mainstream documentary-making in a time of crisis, has been accompanied by a rich strain of theoretical and historical writing on documentary.
