Halftone printing, a process in which images are printed using small dots at different distances apart, made the mass publication of photographs possible. This printing technique was used from the 1880s, starting with the first American news photograph published, above, by the Daily Graphic, until the 1970s when new printing technology began to replace halftone. To better understand how these images were printed, tap the plus(+) signs on the image below to zoom in and see how the tiny dots come together to make an image.
