Audi, Visa, T-Mobile and Lufthansa are among the growing list of companies pulling their advertising from controversial alt-right website Breitbart. Thanks to a grassroots
effort from Sleeping Giants, at least 1,250 advertisers no longer wish to be associated with the site. The campaign encourages Twitter users to publicly name and shame companies who advertise on the
website by drawing attention to screenshots of Breitbart ads.
