"We're experimenting with ways to prompt critical thinking when consuming information online. This small experiment will feature media literacy tips in the form of 15-second skippable ads that will show up before a video," according to YouTube's support page.
The experiment is currently limited to select US users.
For now, YouTube's media literacy ads will only be shown ahead of "a random sample" of videos and Google has specifically stated that these ads appearing before a particular video is "not a judgment" of the channel or the video itself, the report said.
Depending on how the early experiment goes, YouTube will consider the possibility of expanding the program further, it added.
