What happens when you subscribe to a YouTube channel?

Subscribing to a YouTube channel allows you to receive updates every time that channel uploads a new video, which keeps you informed about the latest content from creators you enjoy. When you subscribe, you can see the channel's uploads in your subscription feed, making it easier to keep track of new content without having to search for it manually. This feature enhances the viewing experience by allowing you to follow your favorite channels and engage with their content regularly.

The other options, while related to user experience on YouTube, do not accurately represent what happens upon subscribing. For instance, receiving an email every time a video is uploaded is not a default feature of subscribing, and users typically need to adjust their notification settings to receive emails. Additionally, there are no charges associated with individual videos just because you subscribe to a channel, as YouTube is primarily a free platform with advertisement-supported content. Finally, downloading videos for offline viewing is not a function tied to subscription status; this feature exists only within certain conditions and typically requires a YouTube Premium membership.
