Image description: This image, titled “Terrific Pounding Of German Lines by British Howitzers in the Battle of the Somme in 1917,” was published in the New York Times. During the World War I era (1914-18), leading newspapers took advantage of a new printing process that dramatically altered their ability to reproduce images. Rotogravure printing, which produced richly detailed, high quality illustrations—even on inexpensive newsprint paper—was used to create vivid new pictorial sections. Publishers that could afford to invest in the new technology saw sharp increases both in readership and advertising revenue.
