Since a lot of people watch videos on their mobile via social media networks they see them without sound. So they started making "videos with big texts/captions/subtitles on the screen" (e.g. Tech Insider). How to call them: "Mobile videos"? "Social videos"? "Social media videos"? "Text videos"? Is there an agreed upon term?

Does anyone know since when exactly this trend started and which big media producers were early adopters?

There are basic rules to get the most optimal results.
But I often still find these texts blocking the visual experience, resulting in an inferior video, wishing the texts were just annotations you can remove.
What do you think?
