How it happened: Earlier this year, Google announced it would be shutting down Google+ after a Wall Street Journal report revealed that a software glitch caused Google to expose the personal profile data of 500,000 Google+ users. Then again in December, Google revealed it had experienced a second data breach that affected 52.5 million users. Google has now decided it will shut down Google+ for good in April 2019.
