Messaging App KakaoTalk Hits 100 Million Users

KakaoTalk, the increasingly popular South Korean mobile messaging app, announced Tuesday that it hit the 100 million global registered user mark just over three years after launch (South Korea itself has a population of only 50 million). The app is one of a number of mobile messaging services growing in popularity in recent months, facing stiff competition from the 250-million-user-strong WhatsApp and more recent competing service MessageMe. Facebook has also stepped up its messaging game in the past year, updating its Messenger app with more features on a regular basis.
