LINE Messenger

In March 2011, Japan was hit by an 8.9 magnitude earthquake that initiated a 30-foot high tsunami, triggering a nuclear meltdown of the Fukushima Daichi plant.

 By the end, more than 18,000 people had been confirmed dead and the elements had completely demolished large portions of Japan’s phone system, leaving citizens no way of contacting loved ones to see if they were okay. Months later, LINE Messenger, a subsidiary of South Korean internet company Naver, was launched.

Providing free IM and calling through various devices, LINE soon became the world’s fastest-growing social network in the area – exceeding Twitter use within a year. Though widely accepted as a messaging app, LINE has helped thousands of users stay in contact in emergency situations.
