3M launched the product as "Press 'n Peel" bookmark in stores in four cities in 1977, but results were disappointing. A year later, 3M instead issued free samples directly to consumers in Boise, Idaho, with 94 percent of those who tried them indicating they would buy the product. The product was sold as "Post-Its" in 1979 when the rollout introduction began, and was sold across the United States from April 6, 1980. The following year, they were launched in Canada and Europe.
