...Nike is one of the largest public sportswear and equipment suppliers, with the leading edge in athletic sneakers, apparel, and sports equipment in the world. Nike has been ranked the most powerful sports brand by Forbes magazine, in early 2011. Nike started out as a small distributing company for Asics and now has become a global success. In 1964 Bill Bowerman, the coach of the track and field team for the University of Oregon, as well as one of the runners Phil Knight, started distributing running sneakers for the company “Onsitsuka Tiger” (now known as Asics), in the back of Phil’s car. With profits increasing and popularity growing, by 1967 Blue Ribbon Sports was opening their first retail store in Santa Monica, California. During 1971, Blue Ribbon Sports started to expand, and Phil Knight and Bill Bowerman started preparing their own footwear line. The infamous swoosh was developed in 1971 by Carolyn Davidson. This was the start of Nikes journey to becoming the most powerful sports company in the world today. The first shoe released to the public was a soccer shoe named Nike, which was released in the summer of 1971. Early 1972 the first line of Nike shoes was released. In 1978 Blue Ribbon Sports officially renamed itself Nike. The waffle design was Nike’s first self-designed product.

...O’Rourke for their helpful comments and assistance during this project. 1 1. Introduction How should global corporations behave in the new international world order? What constitutes good corporate citizenship in a world where the stakeholders are diverse and dispersed around the globe and where no clear or consensual rules and standards exist? These questions shape the behavior of most multinational corporations (MNCs) today. Although multinationals are eager to pursue the opportunities of increased global integration, they are increasingly aware of the reactions which their strategies induce – both at home and abroad. Thus, they tread warily, lacking clear and agreed-upon definitions of good corporate citizenship. Through a case study of Nike, Inc. – a company that has come to symbolize both the benefits and the risks inherent in globalization – this paper examines the various difficulties and complexities companies face as they seek to balance both company performance and good corporate citizenship in today’s global world. 1.

In 1985, consumers in the United States alone spent $5 billion and purchased 250 million pair of shoes.2 In 2001,...

...Most people are familiar with the Nike logo. Most people also know that Nike is a multi-million dollar company that sells name brand shoes worldwide. Millions of pairs of Nike shoes are sold daily, but what people don’t know about Nike shoes is how and where they are made, who makes them, and how Nike spends its money in this process. According to the “Sweatshop Fact Sheet,” Tiger Woods is paid over fifty five thousand dollars a day to be their spokesman. Another famous person that is a spokesman for Nike is Michael Jordan. According to the article “Running Away With the Profits,” (Environmental Action, Academic Search Elite), Michael Jordan is paid twenty million dollars in endorsement fees. Big name sport teams advertise Nike to appeal to the common person. Indonesia is one of many countries around the world that is home to numerous Nike factories. Indonesia is a third world country of 214 million people. The main part of the economy is farmers, with half of these being the labor force. This happens to be an ideal country of choice for Nike to set up their factories for manufacturing their shoes. It allows Nike to take advantage of the local people. These people need to work in these factories to make a living, and they are stuck with the poor working conditions that Nike has provided. One way in which Nike is taking advantage of their workers is through long and hard work hours. According to the article: “We are not machines,” the Nike’s code of conduct states that...

The company started out as an American based footware distributor and evolved globally overtime to include not only footwear, but also apparel and equipment. Nike is one of the most recognized brands in the world and many are extremely familiar with their tag line “Just Do It”. Nike has capitalized on first mover advantage over the years and led the market in innovation. Nike competes in a saturated market with many traditional and potential competitors. To maintain future success Nike needs to focus on new strategies. Nike, who also owns Hurley, Converse, Bauer, and Umbro has several traditional competitors including Reebok, Adidas, UnderArmor, New Balance and Puma. Any company that produces athletic footwear or athletic apparel is a competitor to Nike. Nike also sells sunglasses and fitness equipment. Nike also faces potential competition with other shoe or apparel manufacturers. Sketchers had traditionally produced more fashionable everyday footware but has been extremely focused in the last few years on athletic footware. Their Shaper brand is now widely popular for consumers who like to walk for exercise and their cross-training and running shoes are gaining popularity.

...German magazine pointed out that the signature Nike air pocket included more than just air it also contained sulfur hexafluoride, or SF6 a potent greenhouse gas more commonly linked to older refrigerators and air conditioners. SF6 breaks up slowly in the atmosphere, which means that even very small amounts have a significant environmental impact. Estimates suggest that at the peak of SF6 production in 1997, Nike air footwear carried a greenhouse effect equivalent to the tailpipes of 1 million automobiles. It took Nike almost 14 years to devise a new air pocket that was a light, durable, and shock-absorbing as the SF6 version. The breakthrough wound up utilizing nitrogen, held in by a redesigned sole that includes 65 wafer-thin layers of plastic film. The new approach, which debuted with Nike’s Air Max 360, allows the air pocket to stretch throughout the sole, giving even more comfort at even less weight. The company has also devised a program that calculates an environmental impact rating for each shoe, based on use of toxic adhesives, curbing of waste, and use of recycled materials. Even the Air Jordan arguably Nike’s flagship shoe was designed with environmental impact in mind, such that the shoe’s sole consists of ground up bits of old Nike sneakers. You won’t see these issues discussed in television or print ads for Nike shoes, however. Unlike Wal-Mart or General electric, which aggressively trumpet their “GREEN” initiatives, NIKE prefers to deemphasize...
