Laura Ingraham faced an advertiser boycott mainly due to a controversy involving her comments about Parkland school shooting survivor, David Hogg. In March 2018, Ingraham tweeted a remark that mocked Hogg for being rejected from several colleges, which prompted widespread backlash and a call for a boycott of her show, "The Ingraham Angle" on Fox News source.

Several major companies, including TripAdvisor, Wayfair, and Nutrish, pulled their advertisements from her show in response to the incident. Despite the advertiser boycott, Ingraham continued to maintain high ratings, suggesting that her popularity with viewers was unaffected by the controversy, although the financial impact on her show was evident due to the loss of advertisers source.
