Subtitles, which are the text that appears on screen showing what is being said, make a real difference for several reasons. A large number of people watch videos with the sound off, especially on mobile while in public spaces. Subtitles also make content accessible to people who are hard of hearing or who speak a different language. Platforms like Instagram and TikTok have shown that videos with on-screen text tend to get watched longer, and watch time is one of the things algorithms pay attention to. Do you think subtitles are now a basic requirement for video content or still optional?
