My Mom and Dad are avid TV watchers, and now my octogenarian father does have significant hearing loss. We've been using subtitles for decades, probably since the 90s when I started to play with the settings on our newly-purchased TV sets. We enjoy it, especially because we watch a lot of British TV, and although we are quite accustomed to many varied accents from around the Empire, subtitling definitely helps with the interesting turns of phrase, the barely-intelligible asides, and comprehension in general. I also love watching Spanish subtitles to learn the language better. However, I do tend to disable them on YouTube, because they distract and detract from the viewing experience when they are completely unnecessary.
