When people go to the area of communication, we think about voice call, short messages and internet chatting(including instants messages). But if we define communication is an interaction between people and includes all kinds of behaviors from this interaction like social networking, the area of communication is widened.
Former days, there’s a few cases but one-to-one communications such as mail and dialogue. This one-to-one communication is evolved into one-to-many communication by the advent of media and internet. In the name of media which specifically includes broadcasting and newspaper, it’s natural for many people to receive one voice. And this communication is virtually applied to other area-cyberspace.
The world of SNS(Social Networking Service) pursued connectivity through virtual relationship. It gives an important implication that people want to be interconnected. And it would be improved to be many-to-many communication. MMORPG is the other expression of improved communication inlcuding 2nd life.
What will be the next after many-to-many communication? Richness in communication using hologram in Starwars would be an answer. And one of other key concepts is breaking the wall between real and virtual world. This trial is realized recently by the adventurous player like foursquare.com. I am not sure it would be prosperous and popular in near future. What I am sure about is the approach is very efficient and fresh.
