Alongside her television career, Norville has frequently moonlighted as a writer. She served as a contributing editor to "Inside Sports" magazine in the 1980s and as a contributing editor to "McCall's" magazine from 1991 to 1993. She published the "New York Times" best-seller "Thank You Power: Making the Science of Gratitude Work for You" (Thomas Nelson, 2007), featuring the benefits found by research on gratitude. This was preceded by "Back on Track: How To Straighten Out Your Life When It Throws You a Curve" (Simon and Schuster, 1997), which drew on her earlier experiences on the "Today Show".
