Post it-notes

Post-it® Notes were invented in the 1970s at the 3M Company in Minnesota quite by accident. Researchers in 3M were working on developing different types of adhesives, and one particularly weak adhesive was useful.The employees needed to find a use for this notes.One of the employees found a use when he suggested that it should be applied to a pace of paper and use it like a bookmark.

The  adhesive was very sticky and it was reusable.Then the 3M company went to other cities to introduce the new product for the people,sadly that didn't go well.Then they decided to go to another city to take another try.But this time they went only in the offices and similar places,they gave away free samples and return to see if the costumers liked it.They returned a week later,and the product got very famous and the people found a better use.

The product got really famous in the USA,it's fame grew to different parts of the world. After years of success the company realized that they can make different types of the post-it notes with a different color and shape. The 3M made over 400 types of post it notes. That is how the post-it notes were made.
