You're not the only one who gets frustrated when videos buffer too much and too often. Ericsson found that the stress caused by trying to load videos on a slow mobile connection is comparable to the stress you feel while watching a horror movie. The Swedish company discovered that when it conducted an experiment called "The Stress of Streaming Delays." Sure, Ericsson did it to show brands how slow internet affects them, and it's true it only had 30 subjects. But we don't think anyone would disagree that having to endure several seconds to minutes of buffering is frustrating.
