Greatest Invention In History, Post-it Notes, Marks 30th Anniversary

By Robert Paul Reyes

"VHS tapes and walkmans may have been firmly cast into oblivion but another 1980s invention, the Post-it Note, is marking its 30th anniversary this month as popular as ever.

The little yellow square of paper that changed lives was actually the product of an engineering mistake by 3M scientists
who accidentally stumbled upon an adhesive like none other that could stick and be repositioned on just about any surface.

It has remained among the top five best-selling office supplies in the United States each year ever since."


The Post-it Note, also known as a "sticky note", is ubiquitous in offices and homes around the world.

I have seen Post-it Notes stuck on just about everything including microwaves ovens, refrigerators, and bulletin boards. A friend of mine used to stick Post-it Notes on her husband`s forehead when he was sleeping to remind him of important dates.

It`s an excellent memory aid, and it`s impossible to ignore when you stick it on your computer screen. I don`t know how many important dates and deadlines I would have missed if it weren`t for Post-it Notes.

Some people post reminders on their online calendars or leave audio reminders in their cell phones, but nothing will ever replace the Post-it Note.

Happy 30th anniversary Post-it Note! My life would be a jumbled mess without you!
