重要背景介绍：
近日AT&T、强生等大型营销商停止在YouTube、谷歌显示广告网络（Google display network）上投放广告，至此抵制谷歌的行动席卷大西洋（sweep the Atlantic）。谷歌广告危机爆发于上周。英国《泰晤士报》称，一些广告显示在令人反感的视频旁，这些视频的内容或传播仇恨或言辞极为不堪（offensive and inappropriate content）。报道发表后，英国政府和卫报将广告从YouTube撤下（pull advertisements off the video sharing site）。紧随其后，全球第六大广告和营销公司Havas SA将其英国客户的广告从谷歌显示广告网络和YouTube撤下（forsake YouTube）。这周美国各大公司开始密集发声（the issue is taking hold with American advertisers），其中全球最大医疗保健公司强生暂停在YouTube上投放所有全球广告。虽然谷歌已试图阻止事态进一步恶化，推出了新的工具和政策，承诺为品牌商提供更大权限，但由于谷歌广告采用算法投放广告，无法完全确保广告不再出现在极端主义内容旁，许多爱惜名声的公司仍在观望进一步的细节和结果。据估计，此次广告危机将令谷歌损失数亿美元。
