BrainPop

BrainPop.com LLC was founded in 1999 by Avraham Kadar, an immunologist and pediatrician, to explain medical concepts to his young patients using animation, and co-founded by Chanan Kadmon, who served as the company's president, acting CEO and an executive producer, leaving BrainPop in 2003. In 2009, Kadar reorganized the company as BrainPOP LLC. The BrainPop websites display animated, curriculum-based content that supports educators, and are intended to be fun and motivational for students to watch. The sites' movies cover the subjects of science, social studies, English, mathematics, engineering and technology, health, as well as arts and music. The sites also access educational games. As of 2022, BrainPop is used in two thirds of U.S. school districts and in many schools outside the U.S., as well as by parents, homeschoolers and others. Kadar served as CEO from BrainPop's founding until 2019, when Scott Kirkpatrick was named CEO. As of 2011, BrainPop hosted more than 11 million unique visits each month. BrainPop uses an in-house team of educators, animators and writers to produce and continually update the sites, incorporating teacher and parent input.

The site's resources include BrainPop.com, for grades 3–8 and up (ages 9 and up) and BrainPop Jr., for grades K-3 (ages 5 to 9). The sites also offer movies in several languages for regional markets aligned to local educational standards. The site's interactive resource for teachers and homeschoolers, BrainPop Educators, features tips, tools and best practices by and for educators. My BrainPop is a tool for students and teachers to record learning accomplishments, and teachers can track students' progress. In 2009, BrainPop introduced BrainPop ELL (originally called BrainPop ESL), targeted at students learning English as a second language. Schools and parents can use the site to help shape the student's curriculum. BrainPop's free GameUp website contains online games from third-party game publishers that coordinate with the BrainPop, BrainPop Jr. and BrainPop ELL curricula.

BrainPop movies may be used to introduce a new lesson or topic, to illustrate complex subject matter concisely, or for review before a test. Content is aligned to USA state education standards and is searchable by topic or state standard. In addition to movies, the site displays quizzes, educational games, experiments and other related content that students can use interactively to reinforce the lessons in the movies. BrainPop products are compatible with PCs, Macs, projectors and interactive whiteboards, as well as applications for tablets and smart phones. No downloading, installation or special hardware is required. The movies feature recurring characters such as the robot Moby, Tim (a teenager, at BrainPop) and Annie (a younger girl, at BrainPop Jr.). Most of the movies begin with the characters responding to correspondence and end humorously, often with Tim getting annoyed at Moby or vice versa.

After the outbreak of the COVID-19 pandemic, BrainPOP offered free access to the site to affected families, teachers and schools. According to Kadar, traffic and subscriptions to its websites greatly increased.

On October 11, 2022, Kirkbi A/S, the private investment and holding company that owns a controlling stake in Lego, acquired BrainPop for $875 million. Kirkpatrick continued to act as BrainPOP's CEO, and Kadar remained on the board of directors; the same team continued to operate BrainPop independently. BrainPop was a nominee for a Shorty Award in 2025. In 2026, the Trump administration posted a video depicting the BrainPop characters Tim and Moby wearing MAGA hats and promoting the administration's efforts to dismantle the U.S. Department of Education; the post drew a Community Note on X stating that the administration's video is not a publication of BrainPop, which "creates non-partisan" animations "and prohibits unauthorized use of its characters". BrainPop responded to the video by posting a lesson with Tim and Moby introducing the topic of copyright.
