A Brief History of Sticky Notes

A Brief History of Sticky Notes

Believe it or not, the sticky note was accidentally conceived, but it became one of the popular and staple pieces of office equipment over the last four decades or so.

It all began when a scientist at 3M was researching adhesives. At the time, the scientist was tasked with discovering a new adhesive that was bigger, stronger, and tougher than 3M already had.

During their experiments, they created a light-duty adhesive that worked well at attaching pieces of paper on flat, clean surfaces but didn’t create an unbreakable bond.

At first, the adhesive didn’t catch on, and the inventor had trouble finding practical uses for the light-duty sticky materials.

Coincidentally, another 3M scientist, who attended Sunday mass, had trouble keeping the hymn sheets in place. When the two met up and discussed their conundrum, they had a Eureka moment together.

3M launched their sticky-note product, which was known as Press n’ Peel at the time, but it didn’t become an instant hit. It wasn’t until the product reached a wider audience and received overwhelmingly positive reviews Press n’ Peel became a success.

And the rest, as they say, is history.
