Technology growth and influence on people #1

I am going to study about how technology grows that quick and how does it affect on people's relationships.I am interested in this topic because I see how people don't communicate with each other. For example can be when a family goes on a dinner everybody is checking their Facebook accounts, emails or just texting. They spend too much time being online and being in the virtual world. My subquestions and topics are how the technology became such a big part of every person's life and why we are like addicted to technology.
