The title Viscount Northcliffe was created in 1918 in the Peerage of the United Kingdom for Lord Northcliffe, the famous press baron. The viscountcy bore the subsidiary title Baron Northcliffe (1905) and was also a baronet. All these titles became extinct on the death of Northcliffe in 1922.
He was one of the most spectacular of popular journalists and newspaper publishers in the history of the British press.
With his brother Harold (later Viscount Rothermere) as his financial administrator, he increased the circulation of his magazine in five years to more than a million copies a week.
His newspaper campaigns during World War I, particularly those concerning faulty munitions, national conscription, and food rationing, were determining factors in England's conduct of the war, and his support of Lloyd George in 1916 was instrumental in bringing the downfall of the Asquith government.
