Dr. Seuss Digital Books Launch New Record and Share Feature
Users can now record themselves reading the Dr. Seuss story, and then share the recording with family and friends that also own the digital book. If Mom or Dad are away from home on a business trip or deployed in the military, the app allows parents to virtually read their children a bedtime story. The reverse works as well, with a parent or grandparent receiving an audio file of their child or grandchild reading Green Eggs and Ham to them.
