LOS ANGELES--(BUSINESS WIRE)--

Glancy Prongay & Murray LLP ("GPM") announces an investigation on behalf of Facebook, Inc. ("Facebook" or the "Company") (NASDAQ: FB) investors concerning the Company and its officers' possible violations of federal securities laws.

On or around April 2015, Facebook allegedly found errors with the advertising and content metrics used to bill advertisers on its platform. The Company allegedly hid these problems from customers-advertisers, and the investing public. More recently, around November 2016 the Company announced a decrease in advertising revenue. This decrease in revenues allegedly resulted from problems with its advertising platform, and on this news Facebook stock fell sharply in value.
