Post+it+Notes



Post-it® Notes ❶ Post-it® Notes were invented in the 1970s at the 3M Company in Minnesota quite by accident. Researchers in 3M were working on developing different types of adhesives, and one particularly weak adhesive, a compound of acrylate copolymer microspheres, was developed. Employees of the 3M were asked if they could think of a use for a weak adhesive which, provided it didn’t get dirty, could be reused. One suggestion was that it could be applied to a piece of paper to use as a bookmark that would stay in place in a book. Another use was found when the product was attached to a report that was to be sent to a colleague with a request for comments on the report; the colleague made his comments on the paper attached to the report and returned the report. The idea for the Post-it® Notes was born. ❷It was decided within the company that there would be a test launch of the product in 1997 in four American cities. Sales of this innovative product in test cities were less than stellar, most likely because the product, while innovative, was also quite unfamiliar. A final attempt was then made in the city of Boise to introduce the product. In this attempt 3M salesmen gave demonstrations of the product in offices throughout Boise and gave away free samples of the product. When the salesmen a week later returned to the offices where the product had been demonstrated and given away, a huge percentage of the office workers, having noted how useful the simple little product could be, were interested in purchasing it. Over time, 3M came to understand the huge potential of this new product, and over the next few decades more than 400 varieties of Post-it products – in different colors, shapes, and sizes- have been developed. 3.
