CRM is different from corporate philanthropy because the money gifted is not an outright gift to a nonprofit and therefore is not tax-deductible.
The term, "cause-related marketing," was used first by American Express in the 1980s in regard to its campaign to raise money to help restore the Statue of Liberty. American Express made a one-cent donation to the Statue of Liberty whenever an American Express charge card was used. The result was a 45% increase in the number of new card holders and card usage increased by 28%. Of course, millions of dollars were raised for the Statue of Liberty.
CRM is both useful and controversial. Questions raised include the ethics of lending a nonprofit's name and reputation to corporations.
