Root Causes
Google+ launched June 2011 with fanfare and forced integration across Google products. Engagement remained low — average session under 5 seconds according to internal metrics leaked to WSJ. A March 2018 API bug exposing user data to third parties, followed by a second incident in November 2018, forced Google to announce shutdown of the consumer product. Google+ consumer service ended April 2, 2019. Enterprise version continued as Google Currents until 2023.
