After years of product development, 3M introduced the concept of Post-it® Notes in four major markets in 1977. But, without actual samples in hand to try, consumers didn't catch on. A year later, 3M blanketed the Boise, Idaho, market with samples upon samples of Post-it Notes. After trying the notes, more than 90 percent of users said they'd buy the product themselves. The test was a success! By 1980, Post-it Notes were being sold nationally. Today, they're used and enjoyed throughout the world. The Post-it Brand has also expanded into many new product lines including Post-it Super Sticky Notes, Post-it Dispensers, Post-it Flags, and Post-it Easel Pads, among many more!
