The social messenger hype generation

Recently many new TV advertisements for instant messaging services on mobile apps came out. They came out like wildfires. First was WeChat, then came Line. Now I can also see Kakao Talk with K-POP boy band Big Bang as ambassadors. Other instant messaging services that I know but I don't see them on TV advertisements include Whats App, Blackberry Messenger and Google+ Hangouts. Advertisements like these came out like wildfires in order for smart phone users to use them more often than normal voice calls and many of the young generation are using them so I call it as "the social messenger hype generation". In the previous decade, instant messaging services were just on computers connected with the internet only. They are Yahoo Messenger and Skype.
