3M created the Post-it Note after developing a low-tack adhesive.
3M scientist Spencer Silver developed a pressure-sensitive adhesive in 1968 that stuck lightly and could be removed without leaving much residue. The adhesive did not initially have an obvious commercial use.
Several years later, 3M researcher Art Fry used the adhesive on small paper bookmarks for his church hymnal. The idea evolved into a repositionable note, and 3M introduced Post-it Notes commercially in 1980.
Post-it is a 3M brand, not the name of the company itself. 3M began in 1902 as the Minnesota Mining and Manufacturing Company and later became known for products in adhesives, abrasives, films, healthcare, and industrial materials. The company’s market value reflects this broad portfolio rather than the note product alone.
