This document presents market research on children's book consumers, focusing on buying behaviors, influences, and media consumption trends as observed over multiple survey waves from 2011 to 2013. Key findings indicate that mobile devices are increasingly impacting purchasing decisions, with girls accessing devices earlier than boys and an overall decline in teen reading for pleasure despite improving attitudes toward e-books. The study highlights a stable children's market where local influences are crucial, but the trend shows consumers making more independent decisions without external input.
