With hundreds of hours of video uploaded to YouTube every minute, there's a lot of great content you might be missing out on. You can subscribe to specific users to make sure you don't miss out on their content, but what about users you aren't even aware of?

YouTube actually makes it possible to subscribe to topics, making it easy to discover new content and YouTubers. But they haven't done a great job of promoting auto-generated topic channels, and unless you know to look for them, you wouldn't know they were there.

YouTube explains how these auto-generated channels are created:

YouTube has auto-generated channels of trending and popular videos that are created by algorithms. On these channels, you'll see a notice in the "About" section that they've been auto-generated by YouTube. YouTube's auto-generated channels have "Topic" as a suffix.

These channels are created by an algorithm. If the algorithm determines that there is enough popular and high-quality content that belongs under that topic, it will be auto-generated.

It appears that content ends up in these auto-generated channels thanks to an algorithm as well. YouTube explains:

YouTube algorithmically determines the central topics in a video and then uses that information to develop great collections of videos for any topic of interest. These channels don't convey any editorial opinion on the part of YouTube.

So how do you find these channels? You're just going to have to use YouTube's search function. So if you're interested in photography as a topic, just search for "photography topic". If the topic exists, it will appear at the top of your search results.

If you're not sure what to look for, just search "topic" on YouTube and you can see what's available. You can then subscribe to these channels just as you would a user-generated channel and will see the newest videos that end up in that channel.
