Google+
The social network everyone was signed up to and nobody used
Google+ was Google's all-out attempt to fight Facebook, launched on 28 June 2011 and force-integrated into YouTube, Gmail and search. Despite hundreds of millions of created accounts, 90% of sessions lasted under five seconds. Google announced its closure after an API data exposure and shut it down on 2 April 2019.

How it looked

Ownership
Why it shut down
Official line: Google announced the consumer shutdown in its Project Strobe review, citing "significant challenges" and "low usage": 90% of user sessions lasted under five seconds. An API bug that exposed up to 500,000 users' data set the timetable.
Our analysis: Google+ failed years before it closed: forced integration created hundreds of millions of accounts but no community. The 2018 API data exposures, and the decision not to disclose the first one, merely fixed the shutdown date and moved it forward once more bugs surfaced.
History
The Facebook killer
Google+ launched in June 2011 with real innovations (Circles for granular sharing, Hangouts for group video) and the full weight of the company behind it. That weight became the problem: sign-ups were forced through Gmail, YouTube commenting required a G+ account from 2013, and employee bonuses were tied to "social". Google could manufacture accounts by the hundreds of millions; it could not manufacture a reason to come back.
Strobe
By 2015 Google had unwound the forced integrations, and G+ drifted as a ghost town with a small, genuinely devoted photography and tech community. In October 2018 the Project Strobe security review disclosed an API bug that had exposed up to 500,000 accounts' profile data (known internally since March, undisclosed, as the Wall Street Journal revealed). Announcing the fix, Google admitted the numbers: 90% of sessions under five seconds, and scheduled the consumer shutdown. A second bug in December (52.5 million users) pulled the date forward to 2 April 2019, when Google deleted the pages, photos and posts of its last, loyal holdouts. The pattern (force-fed growth, quiet abandonment, sudden erasure) is why
Google Reader veterans saw it coming.
