networkn: Which is interesting, because whilst I have no time for junk instructional video's, I am a visual person. If I can watch someone do something, I'll get it much faster (usually) than reading the concept in a book. I suspect over time, more people have become accustomed to the visual learning method hence it's increasing prevalance.
I find that it depends on the subject. If it's something that I'm pretty familiar with, like a computer, then reading "click this, this and this" is much more tolerable than a video doing the same thing. On the other hand, if it's a subject that I'm not so familiar with then a video can be useful.
My frustration with instructional videos for step-by-step procedure type activities, e.g replacing a battery in a Samsung S6, is having to click pause/play and rewind all the time. This sort of work is much more suited to written instructions with good illustration and or photos, like you'd see on instructables.com where I can proceed to learn about the next step when I'm ready(but that's probably not as financially lucrative, if at all, for the author).
