3M created the Post-it Note and is identified by the stock ticker MMM.
3M developed the adhesive technology behind the Post-it Note after a weak adhesive was created during research by scientist Spencer Silver. Art Fry later recognized that the removable adhesive could hold bookmarks in place, helping turn the idea into a practical office product.
Post-it Notes were introduced nationally in the United States in 1980. The product became one of 3M’s best-known examples of turning research that seemed unsuccessful into a commercially valuable invention.
3M began in 1902 as the Minnesota Mining and Manufacturing Company. Its activities later expanded far beyond mining into abrasives, films, medical products, industrial materials, and consumer goods. The ticker MMM refers to 3M Company on the New York Stock Exchange, not to the Post-it brand itself.
