A global society is, in theory, one which defies the social construct of "to each their own", that is, of world citizens divided and segmented by language, ethnicity, creed, or culture.
Globalization entails extending communication, knowledge, and information to everybody in aims of becoming a collaborative culture where people, despite of their genetic or cultural difference, can still coexist, work, and learn together.
Therefore, a global society can be described as one which has overgrown the tendency to pull apart and has embraced a new culture of sharing and networking with people from all different backgrounds, mindsets, cultures, religions and other differences that in the past were used as excuses to keep us separated.
The advent of the Web 2.0 and the ubiquitous use of computers are the two most monumentally huge steps that helped society move toward social globalization. It is hard to picture this, but there was a time where people would have to actually wait weeks or months to receive any type of communication from anywhere far from them. Nowadays, people just push a button and talk to each other from one continent to another. It is a huge leap that has moved us forward as people and as citizens.
