Developing technologies in the past 50years.

In technology there have been many progresses in the past 50 years. And also the means of communication is thrived which we contact with individuals who lives a long distance from us. First of all, similarity between current and previous methods of communication relates to the form of communication. For example, in the past, both written forms such as letters were frequently used, in addition to oral forms such as telephone calls.  In other words, people nowadays use both of these forms.  Just as in the past, written forms of communication are widespread, for example via email and text messaging. In addition, oral forms are still used, including the telephone, mobile phone, and voice messages via instant messaging services. However furthermore, there are clearly many differences in the way we communicate over long distances, the most notable of which is speed. This is most evident in relation to written forms of communication. To take an example for this, in the past, letters would take days to arrive at their destination.  In contrast, an email arrives almost immediately and can be read seconds after it was sent. In the past, if it was necessary to send a short message, for example at work. To be more accurate, this is different from the current situation, in which a text message can be sent instantenously. On the other hand, another significant difference is the range of communication methods. Fifty years ago, the tools available for communicating over long distances were primarily the telephone and the letter.  By comparison, there are a vast collection of communication methods available today. For instance, the telephone, letter, email and text messages already mentioned, and also video conferences via software such as Skype and social media such as Facebook and Twitter. To be more precise, that kind of apps provide perfect connection among people. In conclusion, methods of communication have greatly advanced over the past fifty years. There is no doubt that technology will continue to progress in future, and the advanced tools which we use today may one day also become outdated.
