History Timeline: Post-it® Notes

For over 40 years, the Post-it® Brand has helped people be more productive, communicate better and express themselves in a number of creative ways.

Yet as universal as these products have become, their beginnings were far from certain. Looking back, the birth of our Canary Yellow phenomenon reminded us of a valuable lesson: perseverance or persistence can be just as important as inspiration when it comes to bringing an idea to life.


From Discovery...

  • Dr. Spencer Silver, a 3M scientist, was busily researching adhesives in the laboratory. In the process, he discovered something peculiar: an adhesive that stuck lightly to surfaces but didn’t bond tightly to them.

    "It was part of my job as a researcher to develop new adhesives, and

    At that time we wanted to develop bigger, stronger, tougher adhesives,"
    said Silver."This was none of those."

    What Silver discovered was something called microspheres which retain their stickiness but with a "removability characteristic," allowing attached surfaces to peel apart easily.

Preaching the Gospel

  • Bunsen burner chemistry and science innovation

    For years, Silver struggled to find a use for his invention. But that didn’t keep him from touting the merits of his creation to colleagues.

    "I came to be known as Mr. Persistent because I wouldn't give up.”

    Meanwhile, Art Fry, another 3M scientist, was frustrated. Every Wednesday night while practicing with his church choir, he would use little scraps of paper to mark the hymns they were going to sing in the upcoming service. By Sunday, he’d find that they’d all fallen out of the hymnal.

    He needed a bookmark that would stick to the paper without damaging the pages.

... To Eureka!

  • Thinking back to a seminar he’d attended on Silver’s microspheres, he had what he now refers to as his eureka moment. “The one where you get the adrenaline rush."¹

    Partnering with Silver, they began developing a product. Once they found themselves writing messages on their new notes to communicate around the office, they realized the full potential of the idea.

    "I thought, what we have here isn't just a bookmark," said Fry. "It's a whole new way to communicate."

Try It, You’ll Like It

  • Two Chemists testing Post-it® adhesive.

    Fry decided to make 3M corporate headquarters his proving ground.

    Fry supplied the entire company with the new adhesive notes.
    Employees loved them.

    3M initially launched the product in four cities under the name Press 'n Peel with mixed results.

The Boise Blitz

  • Marketers decided to put the product directly into consumers’ hands. The massive sampling effort — known as the Boise Blitz because of its launch in Boise, Idaho — was a runaway success. Ninety percent of those who tried the product said they’d buy it.

A Star is Born

  • Dr. Spencer Silver 3M Scientist with Post-it® on Forehead light bulb icon A Star is Born.

    The notes became an overnight success. "It was always a self-advertising product because customers would put the notes on documents they sent to others, arousing the recipient's curiosity. They would look at it, peel it off and play with it, and then go out and buy a pad for themselves."

    Silver said, that like many ground-breaking innovations, theirs was a product nobody thought they needed until they did.

Yellow Gets Its Due

  • On April 6, Silver and Fry’s unsung hero debuted in US stores as Post-it® Notes.

    Its now iconic Canary Yellow color was chosen by happenstance —
    a lab next door only had scrap yellow paper on hand.

    Lee Iaccoa and other Fortune 500 CEOs wrote to say how much they loved them. Post-it® Notes are introduced in Canada and Europe.

Highlighting Greatness

  • Fry was honored with the company's top technical title, corporate researcher. "My biggest reward," he said, "is to see so many people use and appreciate my product." Post-it® Flags were introduced as a new way to organize with color coding, filing and indexing.

1987 to 1996

Staying Power

  • The Post-it® Note celebrated its 10th anniversary and was featured on many lists of top consumer products of the decade.

    Post-it® Easel Pads were introduced. Brainstorming has not been the same, since.

    After 28 years with the company, Spencer Silver, co-founder of Post-it® Notes, retired from 3M with more than 22 US patents to his name.

    Both Silver and Fry finished their careers at 3M having won the highest honors for research as well as numerous awards within the international engineering.
