Facebook’s data scandal has failed to hit the tech giant’s surging advertising revenue, despite the Cambridge Analytica scandal triggering a user revolt and Mark Zuckerberg’s appearance before the US Congress.

Advertiser spending on Facebook was up by an average of 43pc year-on-year over the weeks following the data row, according to advertising analysts.

Since the revelations, several major advertising groups have threatened to boycott Facebook if it doesn’t offer better user privacy controls. The details of 87m Facebook users were obtained by UK political consultants and used in US elections.

But Facebook saw a boost in advertiser spending each week after the scandal broke on March 18, according to media analysts 4C, which monitors hundreds of millions of dollars of ad spending. Spending increased by 7pc in the week of the scandal and 15pc the week after, compared to a six point fall at the same time in 2017.
