Peg- I chose the title of this thread because more people,(Americans, anyway), are familiar with "Tylenol" than "acetaminophen". Most news organizations probably share my view. Relate to the largest numbers of people. I am not singling out the makers of Tylenol. That would be stupid, since acetaminophen is generic and is present in hundreds of over the counter products. But I'd bet that only 25%, at best, of American consumers know what acetaminophen is. I'd bet even fewer know that acetylsalicylic acid is aspirin. A headline of "Acetylsalicylic Acid Reduces Platelet aggregation" would generate less interest than "Aspirin can make you bleed to death".

For good or ill, Tylenol is equated with acetaminophen in the United States. I don't recall which company produces Tylenol, but I bet they are delighted that the generic name "acetaminophen" is so strongly linked to their company. And since they managed to trademark the drug, they will just have to live with any bad news associated with the drug. BlueJay
