paragraph Wrigley's Chewing Gum

1 Wrigley's chewing gum was actually developed as a premium to be given away with other products rather than as a primary product for sale. As a teenager, William Wrigley Jr. was working for his father in Chicago selling soap that had been manufactured in his cents, and this selling price did not leave a good profit margin for the merchants. Wrigley convinced his father to raise the price to ten cents and to give away cheap umbrellas as a premium for the merchants. This worked successfully, confirming to Wrigley that the use of premiums was an effective sales tool.

400-080-6358 www.zhan.com 2 Wrigley then established his own company; in his company he was selling soap as a wholesaler, giving baking soda away as a premium, and using a cookbook to promote each deal. Over time, the baking soda and cookbook became more popular than the soap, so Wrigley began a new operation selling baking soda. He began hunting for a new premium item to give away with sales of baking soda; he soon decided on chewing gum. Once again, when Wrigley realized that demand for the premium was stronger than the demand for the original product, he created the Wm. Wrigley Jr. Company to produce and sell chewing gum.

3 Wrigley started out with two brands of gum, Vassar and Lotta Gum, and soon introduced Juicy Fruit and Spearment. The latter two brands grew in popularity, while the first two were phased out. Juicy Fruit and Spearment are two of Wrigley's main brands to this day.

Paragraph Accidental Inventions

1 A number of products that we commonly use today were developed quite by accident. Two of many possible examples of this concept are the leotard and the Popsicle, each of which came about when an insightful person recognized a potential benefit in a negative situation.

2 The first of these accidental inventions is the leotard, a close-fitting, one-piece garment worn today by dancers, gymnasts, and acrobats, among others. 6A In 1828, a circus performer named Nelson Hower was faced with the prospect of missing his performance because his costume was at the cleaners. 6B Instead of canceling his part of the show, he decided to perform in his long underwear. 6C Soon, other circus performers began performing the same way. 6D When popular acrobat Jules Leotard adopted the style, it became known as the leotard.

3 7A Another product invented by chance was the Popsicle. 7B In 1905, eleven-year-old Frank Epperson stirred up a drink of fruit-flavored powder and soda water and then mistakenly left the drink, with the spoon in it, out on the back porch overnight. 7C As the temperature dropped that night, the soda water froze around the spoon, creating a tasty treat. 7D Years later, remembering how enjoyable the treat had been, Epperson went into Business producing Popsicles.
