CrashCourse

CrashCourse is a widely known educational YouTube channel launched by John and Hank Green (the Green brothers) in 2012. The channel’s mission is to make high-quality educational videos freely accessible to everyone, transforming traditional textbook content into engaging, fast-paced video lessons. CrashCourse videos are commonly used by high school and college students as complementary material, but their clear presentation style also attracts lifelong learners and general audiences.
