Shriver will cover women's social, professional and personal issues as a "special anchor" for NBC News, the network announced Tuesday.
"I've always believed that television can inspire and elevate humanity, and that's my mission with this new partnership," Shriver said in a statement. "I look forward to shining a light on all areas of a woman's experience — from faith and finances, wellness and work, to relationships and the new realities of modern life— and exploring these issues in a way that brings the voices of men into these critically important conversations."
Shriver's other new roles include Editor at Large of NBC News' digital properties, specifically covering women's issues, and being involved in her show Shriver Reports, which airs in early 2014.
Shriver, an Emmy- and Peabody Award-winning journalist, left NBC in 2004. As California's First Lady, Shriver mostly stayed out of TV and movies during the past nine years. In 2009, she executive-produced HBO's four-part miniseries, The Alzheimer's Project.
