The goal was to have the same book read at the same time by 1 million children.
About 700,000 children participated in last year's event. The event was presented by Jumpstart, a nationwide volunteer group that tutors preschool children.
Children & Families Commission of Orange County took the local lead, they partnered with Westfield Main Place Mall, Think Together and Pretend City to reach as many as 12,000 children in Orange County.
Kristen Thompson with The Early Literacy Program told Eyewitness News, "We're here to help children develop a love of books, and really get books in the hands of kids so that we can develop a lifetime of love of reading and literacy at an early age."
Reading events took place throughout the day.
