when did tylenol become popular

Tylenol became popular starting in the mid-1950s. It was first launched as a prescription product for children in 1955 by McNeil Laboratories. Tylenol became available over the counter (OTC) in 1960 for children and in 1961 for adults. By 1975, Extra Strength Tylenol capsules had launched, and Tylenol had become the 5th best-selling analgesic brand in the U.S. By 1976, Tylenol became the #1 brand of OTC analgesic in the U.S. Tylenol's popularity was boosted by its reputation as a safe and effective pain reliever alternative to aspirin and has since become one of the most recommended and widely used pain relievers in the world.
