<P> In the 1920s, under Secretary of Commerce Herbert Hoover, the American government promoted advertising . Hoover himself delivered an address to the Associated Advertising Clubs of the World in 1925 called' Advertising Is a Vital Force in Our National Life ." In October 1929, the head of the U.S. Bureau of Foreign and Domestic Commerce, Julius Klein, stated "Advertising is the key to world prosperity ." This was part of the "unparalleled" collaboration between business and government in the 1920s, according to a 1933 European economic journal . </P> <P> Advertising was a vehicle for cultural assimilation, encouraging immigrants to exchange their traditional habits and tastes in favor of a modern American lifestyle . An important tool for influencing immigrant workers was the American Association of Foreign Language Newspapers (AAFLN). The AAFLN was primarily an advertising agency but also gained heavily centralized control over much of the immigrant press . </P> <P> In 1900, most Canadian newspapers were local affairs, designed primarily to inform local partisans about the provincial and national political scene . The publishers depended on loyal partisan subscribers, as well as contracts for public printing controlled by the political parties . With the rise of national advertising agencies after 1900, a major transformation was underway . The advertisers wanted them to reach the maximum possible circulation, regardless of partisanship . The result was a series of consolidations yielding much larger, largely nonpartisan newspapers, which depended more heavily on advertising revenue than on subscriptions from loyal party members . By 1900, three - fourths of the revenue of Toronto newspapers came from advertising . About two thirds of the newspapers' editorial pages loyally supported either the Conservative or the Liberal party, while the remainder were more independent . Across the board, the news pages increasingly featured more objectivity and bipartisanship, and the publishers were mostly focused on advertising revenues that were proportionate to overall circulation . A newspaper that appealed only to one party cut its potential audience in half . Simultaneously, the rapid growth of industry in Ontario and Quebec, coupled with the rapid settlement of the prairies, produced a large more affluent newspaper - reading population . The result was a golden age for Canadian newspapers peaking about 1911 . Many papers failed during the war era . Advertising agencies in 1915 gained a major advantage with the arrival of the Audit Bureau of Circulations, which for the first - time provided reliable data on circulation, as opposed to the partisan boasting and exaggeration that had been the norm . the agencies now had a stronger hand in bargaining for lower advertising rates . The 1920s became a time of consolidation, budget - cutting and dropping of traditional party affiliation . By 1930 only 24% of Canada's dailies were partisan, 17% were "independent" partisan, and the majority, 50%, had become fully independent . </P> <P> At the turn of the 20th century, there were few career choices for women in business; however, advertising was one of the few . Since women were responsible for most of the purchasing done in their household, advertisers and agencies recognized the value of women's insight during the creative process . Helen Lansdowne Resor at J. Walter Thompson Agency, was one of the pioneers . </P>
