Choose your historical marker to begin the history of newspapers. The first news sheet? The first newspaper? The first daily newspaper?

Pre-history "newspapers" were one-to-one in nature. The earliest variation on a newspaper was a daily sheet published in 59 BC in Rome called Acta Diurna (Daily Events), which Julius Caesar ordered posted throughout the city. The earliest known printed newspaper was in Beijing in 748.

In 1451, Johannes Gütenberg uses a press to print an old German poem, and two years later prints a 42-line Bible -- the significance being the mass production of print products, ushering in an era of newspapers, magazines, and books. By 1500, the genesis of a postal system can be seen in France, while book publishing becomes popular throughout Europe and the first paper mill can be found (England).

Zeitung (newspaper) is a news report published in Germany in 1502, while Trewe Encountre becomes the earliest known English-language news sheet in 1513. Germany's Avisa Relation oder Zeitung, in 1609, is the first regularly published newspaper in Europe. Forty-four years after the first newspaper in England, the Oxford Gazette is published, utilising double columns for the first time; the Oxford/London Gazette is considered the first true newspaper. The first North American newspaper, Publick Occurrences Both Foreign and Domestick, was published in 1690 in Boston.

The 1700s was a century in which market elements were created that encouraged the development of daily newspapers: rising literacy, the formation of nation-states, a developing postal system, the proliferation of urban centers, a rising literary and philosophical tradition emphasising democratic involvement in government, and technologies that supported newspaper production. In short, it was a great news century. The first daily newspaper was The Daily Courant in London, 1702. In 1754, The Daily Advertiser in London uses the first four-column format. France's first daily newspaper appears in 1777, Journal de Paris, while the first United States daily was the Pennsylvania Packet in 1784.

The rise of the middle class transformed newspapers in the 1800s. A penny (US$0.01) buys a New York newspaper in 1833, opening up the first mass market for newspapers. In 1847, the telegraph is used as a business tool, transforming far-away stories. In 1873, an illustrated daily newspaper can be seen in New York. In 1878 the first full-page newspaper advertisements appear, and in 1880 the first photographs are seen in newspapers, using halftones.

With the basic technical groundwork for the modern newspaper in place by the late 19th century, the story of newspapers in the 20th century was about professional development and adaptation to changing consumer and media markets. The story also involved an evolving business model that rode an ever-growing wave of mass-market advertising. Increased profitability and higher revenues attracted publicly owned corporations interested in buying newspapers from descendants of company founders, while simultaneously exposing newspapers to the whims of cash- and profit-hungry stock markets.

By 2000, newspapers were juggling priorities: fragmentation of news consumption, fragmentation of advertising investments, the advantages and disadvantages of being a mass medium, balancing the wants of the marketplace with the company's duty to provide the needs of the marketplace, a journalistic backlash against industry changes, the sheer physicality of ink-on-paper production and distribution versus digital distribution, increasing profit pressure surrounding the core print product, and extension of the company's core brand into other profit centers.
