Sleeping Giants is a social media activism organization aiming to pressure companies into removing advertisements from several conservative news outlets by publicly accusing them of malpractices such as misinformation and hate speech.

[1] The campaign started in November 2016,[2] shortly after Donald Trump's victory in the 2016 United States presidential election, with the launch of a Twitter account aiming to boycott Breitbart News.

[10] Shortly afterward, a New York Times profile of Rivitz and freelance copywriter and marketing consultant Nandini Jammi said the two ran the campaign's Twitter account "along with other still anonymous contributors".

Sleeping Giants' strategy combines traditional approaches to pressure advertisers with direct online activism, aiming to recruit and mobilize a large population of social media users.

[25] In August 2018, Sleeping Giants Oz called on advertisers to boycott Sky News Australia after it broadcast an interview with Blair Cottrell, an Australian far-right extremist.
