If you're like us and get about 1,000 emails a day, most of it junk (and, yes, we have a spam filter), then maybe you've gotten the email that includes this image. But the marketers are taking it one further by using an image of NBC's Matt Lauer and the logos of several networks on which the product has apparently appeared or, more likely, the ingredients in it have been discussed. So, does Lauer know his image is being used to sell a dietary supplement?
