A House subcommittee is investigating YouTube Kids. The panel says the Google-owned video service feeds children inappropriate material in “a wasteland of vapid, consumerist content” so it can serve them ads. In a letter sent Tuesday to YouTube CEO Susan Wojcicki, the House Oversight and Reform subcommittee on economic and consumer policy says YouTube isn’t doing enough to protect kids from material that could harm them. It says YouTube relies on artificial intelligence and creators’ self-regulation to decide what videos make it on to the platform.
