Document 11: Cause-related loyalty marketing: Cause-related loyalty marketing is a recent trend in cause marketing. As the name implies, CLM is the marriage of cause marketing and loyalty programs. Cause marketing occurs when for-profit companies join forces with nonprofits to promote a cause. Recent examples include Nike, Inc. partnering with Livestrong, athlete Lance Armstrong’s cancer-fighting foundation, and Eastman Kodak teaming with stationery designer Bonnie Marcus in support of Breast Cancer Awareness Month. CLM, however, takes these donations and corporate social responsibility efforts one step further, wedding them to thousands of customer loyalty programs. Rather than requiring the outlay of funds from donors, CLM essentially “recycles” loyalty program members’ unused points or miles. It then converts them into usable currency for a cause of the loyalty members’ choosing.

Document 13: Blue Chip Stamps: Blue Chip Stamps started as a trading stamps company called "Blue Chip Stamp Co." They were a competitor to S&H Green Stamps. Blue Chip stamps were a loyalty program for customers, similar to discount cards issued by pharmacies and grocery stores in the digital era. A customer making a purchase at a participating store (typically grocery stores, gasoline stations, and pharmacy chains) would be given stamps in proportion to the size of the purchase. The stamps would be issued by machines next to the cash register. The customer would paste the stamps (which could be licked or moistened with a sponge, like postage stamps) into books. The books could then be taken to a special redemption store and redeemed for merchandise, such as lawn furniture, dining tables, table ware, and many other items. The redemption stores did not keep a full inventory of items, but would order from a catalog on behalf of the customer.
Document 14: Marketing in schools: Marketing in schools is a widespread phenomenon in which schools sign contracts allowing certain businesses to conduct marketing activities in school facilities — primarily advertising. For example, a school might allow only one brand of soft drink to be sold in vending machines on the campus; in return, the soft drink company would provide compensation to the school (frequently money, but it may provide other compensation as well, such as building new facilities or paying for school supplies). The phrase usually refers to arrangements by elementary schools or high schools, rather than higher education; because this marketing is seen as targeting children, it is very controversial. One example of this is Channel One News, a TV show, branded as educational, shown in schools that shows two minutes of advertising. Channel One is shown in over 11,500 middle and high schools across the United States, reaching 7.7 million students.
