I agree that an unboxing video is a strange thing, but I think the reason they are so popular is because the vendors really drop the ball most of the time when it comes to marketing their product. In a perfect world, the vendor would be putting out detailed and thoughtful marketing videos and blog posts that don’t leave the audience with too many unanswered questions. A proper review is best, but an unboxing is sort of helpful when there is not much else to help you understand the product.
