Root Causes
Path launched November 2010 as an intimate social network limited to 150 friends. It hit 15M users by 2014 but hit growth ceiling as Facebook and Instagram absorbed casual users. A 2012 privacy scandal (uploading users' contact books without consent) drew FTC fines. Korean firm Daum Kakao acquired Path in May 2015 for undisclosed sum. Kakao shut Path down October 18, 2018.
