Up to recently in human history the only method of communication open to most people was that of talking with someone or a group of people who you see at the time you were doing so.
Writing was also available, but most people did not have access it books, etc because they were too expensive, having to have been written by hand and in addition most people couldn’t read, even if they could afford it. But with the invention of the printing press and more people receiving an education a new way of communicating, albeit only one way was opened up.
Then came the postal service with someone writing to someone who lived in another part of the country and eventually even in another country and receive a reply back. A further advance came with the telephone and the TV being added to books as a One Way Communication, and more recently the computer and the internet.
This is both a one way communication, but also a 2 way communication, with email, interactive blogs, etc. There is also mobile phones, with more people using texting than actually talking. And the same applies to web based phone services such as Skype.
But as with everything else on the internet one person sees a need for something and then someone else recognises its potential and produces a program that allows other people to do things with it that the orginator didn’t think of.
In another post we will look at one such program that utilises Skype, but in the next one you will be introduced to a program that offers help to people suffering from the present economic situation.
