Advertising played a vital role in the
change of the American economy from one in which most goods were produced and
sold locally to one developed mainly by brand names and products sold
nationally. Before the 1880s, most advertisements consisted entirely of print. The print itself was primarily informational: it described the product and where it could be achieved. The few images that ads contained were highly stylized. Very few ads featured slogans (口号,标语) or brand names. Beginning in the 1890s, however, advertisements experienced a great change. They began to look like advertising today, focusing on visual images, slogans, catch-phrases, and importance of individual’s health and psychological wealth. The J. Waiter Thompson advertising agency sold Scott tissue by warning consumers of "the troubles caused by harsh toilet tissue". Luc A. They shifted American values. B. They led American people to consumption. C. They made the Americans realize social problems. D. They shaped the American culture into one oriented to visual images. [判断题]未设置好防护可以上道作业。
