The term newspaper became common in the 17th century. However, in Germany, publications that we would today consider to be newspaper publications, were appearing as early as the 16th century. They were discernibly newspapers for the following reasons: they were printed, dated, appeared at regular and frequent publication intervals, and included a variety of news items (unlike single item news mentioned above). Early forms of news periodicals were the so-called "Messrelationen" ("trade fair reports") which were compiled twice a year for the large annual book fairs in Frankfurt and Leipzig, starting in the 1580s. Nevertheless, the German-language "Relation aller Fürnemmen und gedenckwürdigen Historien", printed from 1605 onwards by Johann Carolus in Strasbourg, is commonly accepted to have been the first newspaper. The emergence of the new media branch was based on the spread of the printing press from which the publishing press derives its name. Historian Johannes Weber says, "At the same time, then, as the printing press in the physical, technological sense was invented, 'the press' in the extended sense of the word also entered the historical stage."
