Information panel providing topical context Note: This feature is currently available only in the United States. Users may see information from third parties, including Encyclopedia Britannica and Wikipedia, alongside videos on a small number of well-established historical and scientific topics that have often been subject to misinformation online, like the moon landing.
An information panel providing topical context may appear in search results or on the Watch page of videos. It will include basic, independent third party information about a given topic, and will link to the third party partners website to allow viewers to learn more about the topic.
This information panel will appear alongside videos related to the topic, regardless of the opinions or perspectives expressed in the videos.
I found this while watching moon landing videos and yes, they really do put it on everything.
You would think this is a nice feature to augment youtube but it gets patronizing after awhile.
