began to introduce photos and artwork into its depictions of weekly events. From about 1890, The Illustrated London News made increasing use of photography. The tradition of graphic illustrations continued, however, until the end of World War I. Often, rough sketches of distant events with handwritten explanations were supplied by observers and then worked on by artists in London to produce polished end products for publication. This was particularly the case where popular subjects such as colonial or foreign military campaigns did not lend themselves to clear illustration using the limited camera technology of the period.

Many of the Great Eight publications were closed down after the Second World War; The Sketch, The Illustrated Sporting and Dramatic News, and The Sphere all ceased publication in these years.
