In 1968, Dr. Spencer Silver, a scientist at 3M in the United States, was attempting to develop a super-strong adhesive, but instead he accidentally created a "low-tack", reusable, pressure-sensitive adhesive[1][2] that has been characterized as "a solution without a problem"

Fry then developed the idea by taking advantage of 3M's officially sanctioned "permitted bootlegging" policy.[5] 3M launched the product in stores in 1977 in four cities under the name "Press 'n Peel", but its results were disappointing.[6][7] A year later, in 1978, 3M issued free samples to residents of Boise, Idaho, and 94 percent of the people who tried them said that they would buy the product.[6] On April 6, 1980, the product debuted in US stores as "Post-It Notes".[8] In 1981, Post-its were launched in Canada and Europe.[9]

In 2003, the company came out with Post-it Brand Super Sticky notes, with a stronger glue that adheres better to vertical and non-smooth surfaces.[10] Standard Post-it Brand notes have only partial adhesive coating on the back, along one edge.
