A new group of companies suspended some of their YouTube advertising after finding out that ads were appearing over conspiracy theory videos peddled by radio show host Alex Jones on various InfoWars-related YouTube channels. According to a CNN report, companies including Nike, Expedia, Paramount Network, Wix, ClassPass, the Mormon Church, and the NRA have suspended ads on InfoWars channels after being made aware by CNN that their ads were running over conspiracy theory videos. Many companies involved claim that they had no idea their ads were running over InfoWars content, and many say they used YouTube's advertiser tools in the hope of keeping their ads off such content.
