A few times a day I’ll look over and notice one of my colleagues smiling, laughing, frowning, or making a face for no apparent reason. I chose to investigate what was going on. Being in the video production world, part of our job is to watch videos, so my colleague isn’t really making random facial expressions. He’s reacting to video. Your customers do the same thing. They react to video. It creates an emotional attachment to your company, your product, your brand.
