Meet America's Most Powerful Women In Business

Fortune revealed its annual Most Powerful Women in Business list on Thursday morning.

For the first time in the magazine's history, half of the members run their organizations.

IBM CEO Ginni Rometty takes the top spot. While Rometty doesn't get as much press as some of her peers, she continues to crush it at IBM. This is her third year in a row at the top of the list. Crucially, she's moving Big Blue beyond its legacy products - revenue increased by 69% in both mobile and cloud services last year, Fortune reports.

Women in tech are well represented on the list, which also includes Facebook COO Sheryl Sandberg and Yahoo CEO Marissa Mayer, as are women in retail, with T. J. Maxx head Carol Meyrowitz and CVS president Helena Foulkes ranking near the top.

However, even with the progress in female leadership, the list is a reminder that the glass ceiling is still very much present. Only 4.8% of Fortune 500 CEOs are women.

Here are the top 25 women in business:

1. Ginni Rometty: Chairman, CEO, and President of IBM

2. Mary Barra: CEO of General Motors

3. Indra Nooyi: Chairman and CEO of PepsiCo

4. Marillyn Hewson: Chairman, CEO, and President of Lockheed Martin

5. Ellen Kullman: Chairman and CEO of DuPont
