William Wrigley, the founder of Wrigley Gum, I'm afraid everyone who likes chewing gum doesn't know about American Wrigley Gum. Its "spearmint", "fruity" and "double spearmint" chewing gum of almond and eucalyptus have been selling well in the world for more than 8 years. Wrigley was originally a soap factory in Philadelphia in the late 19th century. Until 1 8 9 1, this factory only produced soap. At first, when selling soap, the factory prepared some small packets of baking powder and chewing gum as gifts to be sent with soap. In 1 8 9 1, William Wrigley Jr. moved his factory from Philadelphia to Chicago. In the process of finding a way for his soap, he found that his customers were far more interested in his chewing gum than in his soap. In this year, he stopped the production of soap and turned to chewing gum completely, which was sold at 5 cents a pack. Little William has a strong sense of advertising. His mantra is "tell them as soon as possible, tell them as soon as possible!" He thinks it is a mistake to rely too much on printed advertisements. He invested a lot of money in bus advertisements, subway advertisements and roadside billboards, and later made full use of radio and television advertisements. Of course, he will not give up spending on advertising in newspapers and magazines. William Jr. was the first person to pack imported food with tin foil and the first person to pack small boxes of products with transparent cellophane. William Wrigley Jr.' s original brands of chewing gum were vassar and Lotta. In 1 9 1 4, he first introduced spearmint-type chewing gum, and then introduced fruit-flavored chewing gum and double spearmint-type chewing gum. This is the name he has used for 5 9 years. Soon, Wrigley's chewing gum occupied 7% of the world chewing gum market. During the First World War, his chewing gum packaged in different languages had been sold to 2 countries around the world. The leaves of the mint he used as raw material are pointed. Therefore, the leaves of this pointed mint have long been an important part of his trademark. In the 193s and 194s, the cartoon characters in his advertisements were all pointed. Since the 194s, he has been using a pair of beautiful twin girls as the basic characters in advertisements. The advertisement of Green Arrow gum in 1 9 4 2 was the work of Otis Chipard, a famous American artist. The twin girls were popular in the United States from 194s to 196s. Chipard De, who entered Wrigley in 1 9 3 2, is a special advertising art planner of Wrigley Company. He created a series of vivid and highly publicized advertisements for Wrigley Gum. Chipard often disagrees with William Junior. Chipard advocates that the image of the picture is enough, and the words are redundant. Little William, on the other hand, advocates that advertisements should have a small amount of words. Even on street cars, subways and roadside billboards, it is no exception. Chipard retired from Wrigley Company in 1 9 6 2.
