IN 1982 SOMEONE POISONED A FEW BOTTLES OF TYLENOL. 7 PEOPLE DIED. J&J LOOKED CLOSER AND FOUND A WAY TO PROTECT THE PUBLIC. THERE WERE MILLIONS OF BOTTLES ON THE SHELVES. THE MANUFACTURER RECALLED THEM ALL, THREW THEM AWAY; THEY CHANGED THE PACKAGING TO PREVENT TAMPERING, RELAUNCHED, AND WERE BACK ON TOP IN 1 YEAR.
