The article I read focuses on the usage of videos as the backgrounds for websites. The content is broken into a pro and a con side. On the con side there is slow loading speed, potential distractions, potential contrast, and irritating audio. While something like irritating audio can be easily fixed, a slow loading speed cannot. If the website takes too long to load, viewers will most likely leave the page.
On the pro side there is SEO optimization, cutting edge design, and the ability to explain difficult content easily. The article goes more into detail about this technology showing off the company and making it seem trustworthy.
The article does not give a specific conclusion, as it varies per site.
