The advertiser boycott against Fox News host Tucker Carlson appears to be having a significant impact on his primetime show. According to CNN, Wednesday night’s episode of Tucker Carlson Tonight had four commercial breaks—down from the usual five—with just 20 regular ads (not including in-house promos for Fox content). The week before Carlson said immigrants were making America “dirtier,” his show was averaging 36 regular ads per broadcast. More than two dozen companies have announced that they will no longer place ads on Carlson’s program due to his inflammatory immigration rhetoric. The host has refused to apologize for the comments and Fox News had defended him against “far left activist groups with deeply political motives.”
