Brentwood-based Breitbart News Network has witnessed a more than 90 percent drop in advertising sales revenue in the last three months, fueled by its alt-right agenda and support for President Donald Trump, according to DigiDay.

Breitbart now has 26 companies advertising on its website, down from a high of 242 brands in early March, according to Digiday, which attributed its data to advertising research firm MediaGazer. The source of the ads has also changed from media or retail brands to more conservative, politically charged entities, including website American Patriot Daily.

However, companies such as Amazon.com and Google still advertise on Breitbart’s site despite mounting pressures from employees and the public. Traffic to the conservative news site has also dropped substantially.

Breitbart’s unique visitors plummeted to 10.8 million in April after skyrocketing to more than 16 million after the election.

Larry Solov, Breitbart’s chief executive, has said the company generates most of its revenue through ads, specifically geo-targeted display ads and pop-ups.

Breitbart did not immediately return a request for comment.
