A notice will appear under the videos for any outlets that received some level of government or public funding. It will also include a link to the Wikipedia article about that broadcaster for viewers to glean more information about the news source.

"News is an important and growing vertical for us and we want to be sure to get it right, helping to grow news and support news publishers on YouTube in a responsible way," Geoff Samek, senior product manager for YouTube News wrote in a blog post published on Friday. "This work follows a series of changes we made throughout 2017 to better surface authoritative news content."

Company spokespeople said some labels will appear as soon as Friday, but added that the initiative is still new and developing.

In an example on the YouTube blog, a video from Radio Free Asia -- which is funded by the US' agency, the Broadcasting Board of Governors -- includes a note with an information symbol under the video but right above the title. "RFA is funded in whole or in part by the American government," it states.
