The content of the video in blog form, essentially. I think about my dad. Most YouTube videos now are 10+ minutes, many of them are creeping up into the 20-40 minute range. He hates watching YouTube videos, but reads the news all day. If I find an interesting YouTube video I think he'd get value from, being able to send him a blog post that covers the same topic, in the same level of detail, would be great.

This is the kind of thing I see from YouTubers who want to drive traffic through different channels. People need to be met where they're at. Some people like videos, others like long-form blog posts, others want the information clipped into Shorts or Twitter/Instagram posts, etc. I think being able to transform content from one person's preferred media delivery method into another's is where the value lies for this kind of thing.

Tim Ferriss sometimes has some good examples of what I'm thinking of what I'm thinking about. In this example[0], there is a YouTube video of the TED talk, with a full blog post/article, and then at the bottom if references 2 books he wrote where this was pulled from and talked about more. If a person wants a video, text, or a full book, this post either has it directly or acts as a funnel to get the person there.
