Facebook failed to add North American daily active users and lost European daily active users in the second quarter, amid data leaks, privacy changes and fake news scandals, the company reported Wednesday. In its second-quarter earnings report, Facebook said North American daily active users (DAUs) remained at 185 million, the same as the prior quarter. Analysts were expecting 185.4 million, according to FactSet. European DAUs fell to 279 million in the second quarter from 282 million in the prior period — likely a result of Europe's recently enacted General Data Protection Regulation (GDPR), a set of rules that give users more control over their online data.

Global DAUs continued to increase, rising to 1.47 billion, up from 1.45 billion. Analysts expected 1.49 billion. CEO Mark Zuckerberg revealed on the company's earnings call that 2.5 billion people use at least one of Facebook's apps — including Instagram, WhatsApp and Messenger — every month. Facebook's North American number has fluctuated over the last year, dipping slightly at the end of 2017 before bouncing back.
