How a pediatrician's medical animations became a multi-billion dollar classroom staple

In short: What started as a way to explain medicine to young patients has evolved into a massive educational empire. Today, BrainPop reaches two-thirds of U.S. school districts, using a unique blend of humor, robotics, and curriculum-aligned animation to make complex subjects digestible for millions of students.

Founded in 1999 by immunologist and pediatrician Avraham Kadar and Chanan Kadmon, BrainPop began with a specific clinical goal: explaining medical concepts to Kadar's young patients through animation. By 2009, Kadar reorganized the company as BrainPOP LLC. The platform's success was rooted in its ability to translate complex information into "fun and motivational" content. This pedagogical approach was validated by a 2009 multi-grade study by SEG research, which involved over 1,000 students in New York City and Palm Beach County, Florida. The study concluded that students using BrainPop made significant improvements compared to those who did not.

The brand's reach expanded significantly through diverse products tailored to different age groups and needs. BrainPop Jr. serves children in grades K–3, while the main site targets grades 3–8 and up. The company also offers specialized versions like BrainPop Español, BrainPop Français, and BrainPop ELL for non-native English speakers. To support the professional side of education, BrainPop Educators provides a free hub for teachers to share lesson plans and interact with peers. In 2022, the company reached a major milestone when Kirkbi A/S, the holding company for The Lego Group, acquired BrainPop for $875 million.

At the heart of the brand are its recurring characters, most notably Tim, a teenager who narrates the lessons, and Moby, an orange humanoid robot who communicates in beeps. Moby’s robotic nature allows for imaginative pedagogical tools, such as traveling through time or using a freeze-ray to illustrate scientific concepts. While the content is designed to be non-partisan and curriculum-aligned, the brand has had to navigate modern complexities, such as responding to unauthorized use of its characters in political videos by issuing lessons on copyright.
