The era of modern newspapers begins in the mid-nineteenth century, with the Industrial Revolution, and increased capacities for printing and distribution. Over time, improvements in printing technology, graphical design, and editorial standards have led to changes and improvements in the look and readability of newspapers. Nineteenth-century newspapers were often densely packed with type, often arranged vertically, with multiple headlines for each article. A number of the same technological limitations persisted until the advent of digital typesetting and pagination in late 20th century.
