Video often gives you a better idea of how the product will feel to use, not emotionally, but dynamically.
Take for example Google's "Material Design" in Android L, you can read all the articles you want, but the concept won't make sense until you watch a video of the animation/transitions/etc. There are a lot of products/ideas like that. They say an image is a thousand words, and this isn't a sixty thousand word article.
I think it is silly to suggest that people who prefer video content over an article are "less intelligent." Instead those people want to get an idea of how the product would actually work in reality rather than just eating up all the carefully crafted marketing language within the article.
This is why unboxing videos and amateur product demos are so damn popular on YouTube: They actually give you a true-to-life idea of how a product would be. Articles are too carefully crafted, and seeing the product without the person interacting with the product is only 1/2 the message or less.
