Brent Lang Executive Editor Most people know that social media has become a cesspool of disinformation, a digital hydra that feeds off toxicity and conspiracy theories. But somehow YouTube, the second-most-popular site in the world, has avoided the scrutiny that’s come Twitter and Facebook’s way. “The YouTube Effect,” a new documentary from Alex Winter, could change that. It takes a tough look at the role that the Google-owned service played in everything from the Jan. 6 riot to the 2019 New Zealand mosque shooting by promoting election denialism and white supremacy. “People don’t know that YouTube and Google are the biggest purveyors of disinformation,” Winter says. “One reason is people don’t understand what YouTube is. Is it just a place to watch cat videos, or is it something else? And the second reason you hear about it less is because Google is so deep-pocketed that it has some of the strongest lobbyists in the world working for them. That’s made them less likely to be legislated against.”
