Power comes in many forms. And on Fortune’s 2016 Most Powerful Women list, it also comes in the form of many industries. Just look at the breadth of organizations run by our top 10: four tech companies. Two defense contractors. Two food companies. One financial giant. And one century-old carmaker—GM—led by Mary Barra, who repeats in the top spot on our annual list.

All told, the 22 CEOs (down from our 2015 record of 27, partly because of new C-suite contenders) control $1.1 trillion in market capitalization. There are 10 newcomers or returns—including CEOs Tricia Griffith of Progressive and Vicki Hollub of Occidental Petroleum (but not counting our special bonus MPW: Beyoncé!). We also lost some perennials, including Ellen Kullman, who left DuPont last year; Sheri McCoy, who has struggled at Avon; and Marissa Mayer, who tried to right Yahoo but didn’t succeed.
