Vatican News, is the official representation of the Holy See and the Pope on YouTube which is mostly news. Some of the news content is livestreamed, but there are very few people watching the videos. Some of the videos revolve around the Catholic Church such as having a prayer by the Pope that is pubic which are very long and other messages.
The other videos can show personal experiences with Catholicism by various Christians. There are some world tours by the Pope, and there are non-English language videos such as in Italian. There is a chance that Vatican News has the most subscribers out of all of the country's channels.
The news videos have some commentary, and the travel videos showcase the Pope which are like a third person vlog.
The English version of the Vatican News has fewer subscribers which is called Vatican News - English which pretty much has similar content, but only Vatican News is verified.
