When high-speed rotary presses became available, together with typesetting machinery, it became possible to have press runs in the hundreds of thousands, with frequent updates throughout the day. By 1912, there were 4000 newspapers, printing 5 to 6,000,000,000 copies of the year. New technology made illustrations more feasible, and photographs began appearing. Advertising was now an important feature. Nevertheless, all newspapers focused on their own city, and there was no national newspaper of the sort that flourished in Britain, nor chains owned by one company such as those becoming common in the United States. All the political parties relied heavily on their own newspapers to inform and rally their supporters. For example, there were 870 papers in 1912 pitched to conservative readers, 580 aimed at liberal elements, 480 aimed at the Roman Catholics of the Centre party, and 90 affiliated with the Socialist party.
