FTC says Facebook has been a monopoly ‘since at least 2011’ in amended antitrust complaint

The Federal Trade Commission has filed an amended antitrust complaint against Facebook, alleging that the company violated federal antitrust laws with its acquisition of Instagram and WhatsApp. The new complaint is a more detailed version of a charge dismissed by the court in June for insufficient evidence.

“Facebook has today, and has maintained since 2011, a dominant share of the relevant market for US personal social networking services,” the complaint alleges, citing time spent and active-user metrics on the daily and monthly scale. “Individually and collectively, these metrics provide significant evidence of Facebook’s durable monopoly power in social networking services.”
