WiFi

I think the biggest implications of wireless technology for communication scholars is that it allows people to communicate from anywhere. In the past you would have to basically be with the person to communicate or at best write a letter. Then the telegraph changed things so that as long as each of you had a machine you could communicate with one another. Then the telephone, then the internet, etc. But one thing was in common. You had to be connected by a wire. Cellular technology gave people the ability to call one another from anywhere (within reason considering a tower was necessary) and now the internet and text messaging and video and all kinds of other ways of communicationg are being tacked onto this wirless technology. It's really amazing that no matter where someone is they can talk with someone else. There really is no escape anymore. At any moment somebody can contact you. It's rather unnerving.
