RR Donnelley is the world's largest printing and business services provider. It was founded in 1864 and went public in 1956. By 1995, it generated 60% of its revenues from directories, catalogs, and magazines. In the 1990s, it began a digital division to take advantage of emerging digital printing technologies and created new software tools and target markets for on-demand printing. However, the digital division faced challenges gaining acceptance within the larger company due to unrealized sales expectations and financial pressures.
