In the twentieth century, slides and projectors were used for a variety of private, commercial, and artistic uses.

Slide Comparisons in EducationDual slide projection is a pedagogical tool used by educators to make comparisons. Heinrich Wolfflin founded the comparative mode of analysis used in art history to make aethetic judgments, which Pamela M.

Performance ArtSlides were used in performance art by John Cage as early as 1952 in "Theater Piece No. 1" at Black Mountain College. Cage used slides to structure the timing of the happening's actions. Other performance artists would later add liquids to slides before projecting them to give them animated and organic qualities.[4] Pictured is a performance by John Cage and Ronald Nameth in 1969 at Assembly Hall, University of Illinois, Champaign-Urbana that included 8,000 slides.
