YouTube is a video-sharing platform founded in 2005 and acquired by Google in October 2006. It supports long-form video, live streaming, the short-form Shorts format, and creator monetization, and operates localized versions in over 100 countries across 80 languages.
Reported scale
YouTube publishes activity figures rather than user counts: more than 20 million videos uploaded daily, and Shorts averaging over 200 billion daily views. As of January 2026 it states it has led U.S. streaming watchtime for nearly three years. Monthly-user figures widely attributed to YouTube are third-party estimates.
The recommendation algorithm and the radicalization question
YouTube’s recommendation system is often described as leading users from mainstream political content toward progressively more extreme material — the “rabbit hole.” The largest peer-reviewed study of actual viewing behavior does not support that account. Hosseinmardi and colleagues, analyzing individual-level browsing data in PNAS (2021), report: “We find no evidence that engagement with far-right content is caused by YouTube recommendations systematically.” They further found no clear evidence that “anti-woke” channels function as a gateway to far-right content, and concluded that consumption of political content on YouTube “appears to reflect individual preferences that extend across the web as a whole” — that is, viewers arrive with existing preferences and often from off-platform referrals, rather than being routed there by the recommender.
This is a live scholarly dispute rather than a settled question, and the finding is about systematic causation across a population, not about whether any individual was ever recommended extreme content.
Elections policy
YouTube’s published elections misinformation policy prohibits three things: content that misleads voters “about the time, place, means, or eligibility requirements for voting”; false claims about the technical eligibility requirements of current candidates and sitting officials; and content encouraging others to interfere with democratic processes. Notably, the policy as published does not prohibit claims that a past election was fraudulent.
