Remember that fake scientific journal I wrote about? The one that looked like a real research journal, with articles made to look like research papers, and published by Elsevier, major scientific publisher? The one that Elsevier got paid to publish by pharmaceutical company Merck in order to push the now withdrawn medication Vioxx?
That magazine was, as it turns out, not an isolated occurrence. They've owned up to another six such journals and a whole imprint of fifty journals that is dedicated to deliberately push marketing (read that last link for a pretty balanced take). I'm sure it's made Elsevier a lot of money. Not doing a whole lot of good for their credibility of course.
