Summary:
- The Post-it note was invented in 1968 by 3M employee Arthur Fry. He was looking for a way to mark pages in his hymnal without damaging the pages.
- Fry's idea was to use a weak adhesive that would allow the notes to be easily removed and reattached without leaving any residue.
- The Post-it note became a popular office supply and is now used in homes, schools, and businesses around the world for making quick notes, reminders, and organizing information.
