A new test YouTube is trying out with some users entices them to subscribe to channels they often watch videos from. As it is now, the YouTube homepage shows the usual mix of recommended videos from channels you follow and those that have content based on things you’ve watched in the past. For some users, they’ve started to see this new text below some videos: “Love *insert channel name*? Never miss an upload!” The subscribe button is placed to the right of the text. Apparently this doesn’t appear for all channels but for those you watch a lot of content from but haven’t subscribed to yet. Hopefully if it does roll out to more users, there is an option that will let you say no. Some might not want to subscribe to specific channels but, of course, being bugged about that at each turn can become annoying.
