In 1968, Spencer Silver, a scientist at 3M in the United States, attempted to develop a super-strong adhesive. Instead, he accidentally created a "low-tack", reusable, pressure-sensitive adhesive for the aerospace industry.{{cite web|url=http://solutions.3mae.ae/wps/portal/3M/en_AE/Post-Its/Post-It/Solutions/History/|title=Post-It® Brand|work=3m.com|url-status=live|archive-url=https://web.archive.org/web/20170202085713/http://solutions.3mae.ae/wps/portal/3M/en_AE/Post-Its/Post-It/Solutions/History/|archive-date=2017-02-02}}{{cite news|url=http://www.inc.com/tim-donnelly/brilliant-failures/9-inventions-made-by-mistake.html|title=9 Brilliant Inventions Made by Mistake|last=Donnelly|first=Tim|date=23 August 2012|newspaper=Inc.|access-date=24 August 2012}}{{cite web|url=http://www.post-it.com/wps/portal/3M/en_US/Post_It/Global/About/|title=About Post-It® Brand|access-date=2013-02-12|quote=The Post-It® Note was invented as a solution without a problem: Dr. Spencer Silver developed a special, repositionable adhesive, but the 3M scientist didn't know what to do with his discovery.|url-status=live|archive-url=https://archive.today/20130411165856/http://www.post-it.com/wps/portal/3M/en_US/Post_It/Global/About/|archive-date=2013-04-11}}{{Cite web |title=The History of Post-it Notes: The Accidents That Led to the Invention of the Sticky Note [INFOGRAPHIC] |url=https://www.stik2it.com/blog/the-history-of-postit-notes-the-accidents-that-led-to-the-invention-of-the-sticky-note-infographic/ |access-date=2023-11-09 |website=Stik2it.com |language=en}} For five years, Silver promoted his "solution without a problem" within 3M both informally and through seminars, but failed to gain adherents. In 1974, a colleague who had attended one of his seminars, Art Fry, came up with the idea of using the adhesive to anchor his bookmark in his hymn book.{{cite web|url=http://web.mit.edu/invent/iow/frysilver.html|title=Inventor of the Week: Art Fry and Spencer Silver|access-date=2007-09-23|publisher=MIT|url-status=live|archive-url=https://web.archive.org/web/20071014051221/http://web.mit.edu/invent/iow/frysilver.html|archive-date=2007-10-14}}{{cite book | title=The Evolution of Useful Things | last=Petroski | first=Henry | author-link=Henry Petroski | pages=[https://archive.org/details/evolutionofusefu00petr_0/page/84 84–86] | year=1992 | publisher=Alfred A.

The original notes' canary yellow color was chosen by chance, from the color of the scrap paper available at the lab next door to the Post-it team.{{cite web|url=http://www.thejanuarist.com/why-are-post-it-notes-yellow/|title=Why Are Post-It Notes Yellow?|access-date=2010-02-25|url-status=live|archive-url=https://web.archive.org/web/20100228173348/http://www.thejanuarist.com/why-are-post-it-notes-yellow/|archive-date=2010-02-28}} Fry provided 3M employees with a prototype of the product, and individuals started exchanging messages, demonstrating the product's communicative effectiveness.

Silver and Fry both concluded their careers at 3M after achieving the highest accolades for their research and receiving numerous international engineering awards.

Alan Amron claimed to have been the actual inventor in 1973 who disclosed the Post-it note technology to 3M in 1974.{{cite web|url=https://www.latimes.com/nation/ct-post-it-note-inventor-lawsuit-20160311-story.html|title=Sticky lawsuit: $400M dispute lingers over Post-it inventor|work=Los Angeles Times|date=March 12, 2016|access-date=March 13, 2017|url-status=dead|archive-url=https://web.archive.org/web/20170314063535/http://www.latimes.com/nation/ct-post-it-note-inventor-lawsuit-20160311-story.html|archive-date=March 14, 2017}}{{cite web|url=http://www.thetimes.co.uk/tto/business/industries/consumer/article4717729.ece|title=Sticky situation as inventor sues 3M for $400m over Post-it Notes|last=Frean|first=Alexandra|date=March 21, 2016|work=The Times|access-date=March 13, 2017|url-status=dead|archive-date=2016-05-09 |archive-url=https://web.archive.org/web/20160509102359/http://www.thetimes.co.uk/tto/business/industries/consumer/article4717729.ece}} His 1997 suit against 3M resulted in a confidential settlement. As part of the settlement, Amron agreed not to make future claims against the company unless the settlement agreement should be breached. However, in 2016, he launched a further suit against 3M, asserting that 3M was wrongly claiming to be the inventor, and seeking $400 million in damages.Alan Amron v. 3M Minnesota Mining & Manufacturing Co. et al., case number 9:16-cv-80125, in the U.S. District Court for the Southern District of Florida. At a preliminary hearing, a federal judge ordered the parties to undergo mediation. The suit was subsequently dismissed, upholding the previous 1998 settlement.{{cite web|url=https://www.law360.com/articles/838227/fla-man-s-400m-suit-over-invention-of-post-it-notes-tossed|title=Fla.

In 2016, the day after the US presidential election, artist Matthew "Levee" Chavez started a collaborative art project called "Subway Therapy".{{Cite web |title=Subway Therapy: a project by Matthew "Levee" Chavez |url=https://www.arcadia.edu/exhibitions/gallery-archive/subway-therapy-a-project-by-matthew-levee-chavez/ |access-date=2023-11-09 |website=Arcadia University |language=en-US}}{{Cite news |last=Rosenberg |first=Eli |date=2016-12-06 |title=Sticky Notes Bearing Election Hopes and Fears Removed from Subway |work=The New York Times |url=https://www.nytimes.com/2016/12/16/nyregion/subway-election-therapy-wall-sticky-notes.html |access-date=2023-11-08}} Levee set up tables and chairs in Union Square Station and invited commuters to express their thoughts and feelings on Post-it notes. Most Post-it notes conveyed people's hopes and fears in response to the election. The public contributed over 50,000 Post-it notes to the subway walls until the project was taken down on December 16, 2016. The New York Historical Society preserved several thousand of the Post-it notes.

Post-it notes have also been used in museums to allow for more public interactivity and participation.{{Cite web |last=Faulkenbury |first=Evan |date=2017-01-09 |title=Sticky notes as tools for public history |url=https://ncph.org/history-at-work/sticky-notes/ |access-date=2023-11-09 |website=National Council on Public History |language=en-US}} In 2016, at the Minnesota History Center in St. Paul, Minnesota, the public wrote their reflections on the life of Prince on Post-it notes and posted them near the exhibit.{{Cite web |date=2017-04-18 |title=Prince's suit from 'Purple Rain' on exhibit again |url=https://www.mprnews.org/story/2017/04/18/prince-display-back-up-at-historical-society |access-date=2023-11-09 |website=MPR News |language=en}} Some Post-it notes were archived by the museum to preserve the public sentiment expressed at the time.

Virtual Post-it notes have been created for computers in the form of desktop notes. These include 3M's own Post-it Brand Software Notes, Stickies in macOS, or Sticky Notes in Windows.{{cite web |url=http://windows.microsoft.com/en-US/windows7/products/features/sticky-notes |title=Windows 7 Features 'Sticky Notes' |access-date=2010-12-25 |url-status=live |archive-url=https://web.archive.org/web/20101224200120/http://windows.microsoft.com/en-US/windows7/products/features/sticky-notes |archive-date=2010-12-24 }}
