On October 7, 2019, Facebook, Inc. agreed to pay $40 million to advertisers after providing inflated video watch time metrics from February 2015 through September 2016.
The class action lawsuit began in October 2016, following Facebook’s September 2016 announcement that the social media platform discovered a metric calculation error. The error resulted in inflated video advertisement costs, and is estimated to have affected 1.35 million advertisers.
