Pizza Hut's iconic Book It! reading program — which is celebrating its 40th anniversary this year — is making its long-awaited return to stores nationwide. In addition, Pizza Hut and Book It! will be giving away 1 million personal pan pizzas throughout October, which is National Book Month, as per Stacey Leasca with "Food & Wine. "

Sometime in 1984, Pizza Hut launched its own reading program called Book It! The idea was to encourage school-age kids to read books and earn free pizza.

Pizza Hut has offered its personal pan pizza as motivation for students to read since 1984, and this month — National Book Month — everyone can cash in on the perks. The Plano-based pizza chain is offering one million free personal pan pizzas with an $8 purchase during October,
