This week, host Charles Nix sits down with Steffi Marty, the Global Director of Brand Identity and Design for Mars Snacking. If that sounds abstract, you probably know the brands she oversees: the Mars Bar, Snickers, Skittles, and M&M's.

Charles and Steffi collaborated on a new typeface for M&M's, released last year, and the two discuss the joys and challenges of managing such beloved and personal brands, why typography is crucial to that, and what she calls a "ruthless discipline to weed out the things that are unnecessary."
