We live in a very visual atmosphere. Our entire culture is built around the ability to immerse ourselves in the things we see around us. Video is one of the best media for advertising because of this.
We create commercials to showcase products, demo reels to promote companies, website video to add more interactivity to online experiences, and pubic service announcements to spread the word.
It's not about making a video. It's about the experience the video gives its viewers. When the creativity fused into that video gets a company and its products noticed and remembered, it's done its job.
