During the Q&A of a presentation at the AdvaMed Advertising and Promotion of Medical Devices conference (slides here), I was asked why I claimed that the word "new" meant within the past six months. I mentioned that FDA had a post noting this and that FTC also had the same position.
On the train home, I decided to hunt down the sources, and this post is the result so I don't have to duplicate the effort again. I didn't realize that FTC's position on the issue went back to 1967.
