According to the law firm press release, Twitter is a global platform for public self-expression and conversation in real time, where any user can create a Tweet and any user can follow other users. The Company’s main source of revenue is advertising. Because advertising revenue is driven by the total number of users on the platform and, equally as important, the level of engagement of such users, the Company and analysts have focused closely on metrics measuring total users and user engagement. Twitter reported two primary user metrics: Monthly Active Users or “MAUs” (a measure of the total user base) and timeline views (a measure of user engagement). Prior to the beginning of the Class Period, Twitter announced that it would discontinue reporting its primary user engagement metric, timeline views, stating the reason for the change was that the metric was an unrepresentative measure of user engagement and no longer reflective of Twitter’s business.
