The clips are produced by Future Advocacy and intend to show that people can no longer necessarily trust what they see in videos, not just to question what they read and hear. Boris Johnson has a message for you.#GE2019 Jeremy Corbyn has a message for you.#GE2019 In the era of fake news, people are becoming increasingly aware not to believe everything they read.

Facebook will not remove a deepfake video of CEO Mark Zuckerberg falsely portraying him claiming to control the future thanks to stolen data - similar to the platform's refusal to take down a doctored video of Speaker of the House Nancy Pelosi in May. The video created by Bill Posters and Daniel Howe in partnership with advertising company Canny is hashtagged '#deepfake,' a term that refers to video or audio with virtually undetectable edits made to portray something very different than the original media source. In the edited video which also includes a CBSN logo, Zuckerberg is made to appear to say, 'Imagine this for a second: One man, with total control of billions of people's stolen data, all their secrets, their lives, their futures. I owe it all to Spectre. Spectre showed me that whoever controls the data, controls the future.'
