This monograph examines the extent to which Lord Northcliffe, generally conceded to be the dominant force in the popularization of journalism in Britain and what was once the British Empire, influenced or was influenced by American developments in journalism. The first section, entitled "The Legacy," briefly reviews the popular press in England. The remaining sections of the monograph afford a biographical sketch of Lord Northcliffe and a discussion of his career, with emphasis given to his influence by and on American journalism at the beginning of the twentieth century.
