The document discusses how the human brain is overloaded with information due to the exponential growth of data. It highlights that visual content like explainer videos and infographics are effective ways to communicate and attract attention because people remember 20% of what they read but 80% of what they see. Explainer videos use techniques like whiteboarding, photography and animations to simply explain complex topics, and have become increasingly popular on YouTube. Infographics also visually convey information through static and interactive designs, and are shared more widely on social media than text-based articles. Both explainer videos and infographics are powerful visual communication tools in the age of information overload.
