In the 1840s a new type of publication-the pictorial news weekly – arose in Britain and the United States. A. Mass production of the large, finely engraved illustrations that characterized pictorial weeklies was made possible by improvements in printing that made it easier and faster to create metal plates. B. As photography gained in popularity throughout the world in the 1840s, photographic portraits largely replaced portraits by woodblock engravers. C. An increasing cultural concern for propriety and formality resulted in a shift away from the comic and imaginative illustrations of earlier decades. D. Soon after the introduction of the daguerreotype in 1839, early photographs were used to aid in the creation of illustrations for the weeklies. E. Many of the leading illustrators of books and magazines in the 1820s and 1830s later switched to comic journals because their high-spirted style did not suit the tone of the weeklies in later decades. F. The new magazines attempted to achieve a look of documentary realism by ensuring that their illustrations, especially those depicting scenes full of movement, closely resembled photographs.
