In an "open letter" to advertisers published this morning, Harmelin Media President Mary Meder becomes the latest agency executive to weigh in on the controversies surrounding principal media-buying and agencies pocketing rebates from the media that might otherwise be intended for their clients. Not surprisingly, she's against the practice, and gives some compelling reasons why other agencies -- and their clients -- should be against it too.

In the video embedded above, Meder explains why, and specifically, why now. And what to do next.
