We will update our US ad revenue forecasts for Facebook, Instagram, Snapchat, Twitter and Pinterest in June 2020. For that reason, we’re focusing the discussion in this section on the broader social media market, rather than on individual properties. What Will Happen in Q2. April will see continued social ad spending declines; May and June have a high degree of uncertainty.
Snapchat and Instagram also experienced declines in content-sharing, but the percentage using Pinterest for sharing publicly was higher in 2019 than the percentage who shared content in general in 2017. Twitter was flat in these two metrics.
Instagram user growth will be even stronger in the UK. We expect the number of UK Instagram users to rise by 8.0% in 2019 to 21.0 million. At the start of 2019, however, we predicted that Instagram would begin to experience growing pains this year.
