Established in 1974 and still active in New York, Artists Talk on Art is the art world's longest running and most prolific aesthetic panel discussion series organized by artists for artists. Founded by Lori Antonacci, Douglas I. Sheer, and Robert Wiegand, the forum has presented 6,000 artists in nearly 1,000 documented panels or dialogues. ATOA held its first panel, "Whatever Happened to Public Art," on January 10, 1975 and it drew a "crowd" of 77 people. In the decades that followed, ATOA presented dozens of panels or dialogues a year, tackling such diverse topics as "What is Happening with Conceptual Art," with Louise Lawler and Lawrence Weiner; "Painting and Photography: Defining the Difference," with Sarah Charlesworth, Jack Goldstein, Joseph Kosuth, Barbara Kruger, and Robert Mapplethorpe; "Organizing Arts Activism," with Lucy Lippard; "The Artist and the Epidemic—an information panel about AIDS"; "Cross-generational Views of Feminism"; and hundreds more.
