Instant Messenger-Please, help me to revise it Since the dawn of time, mankind has always been trying to communicate among them. Firstly, our ancestors communicated each other through face expressions, grunts and gestures in every situation, albeit mainly in activities related to courtship display, scent-marking or to show force and authority. However, through communications humans have been able to exchange emotions, feelings, knowledge, and culture and so on. Over the years, different civilizations began to spread along the territories for hunting, gathering or conquering so they needed an organized system of communication that would allow them an effective control of these new territories. The smoke signals is one of the oldest forms of long-distance communication and one of the most known. It is a form of visual communication employed over long distance. Actually, smoke signals were used to transmit news, the proximity of a danger, or even to gather people to a common area. Amerindian made huge bonfires and used the smoke to made signals in order to communicate with other tribe headmen in case of war. Sometimes the signals arrived late or had a different meaning as wind distorted them. Communicating by letters has existed from the time of ancient India or ancient Egypt and they have been used intensely during the years. However this method has become less important as a routine way of communication. . Roman used to send letters to share information through all over the empire. It took a large time to communicate and could have catastrophic consequences if they weren´t in time, especially with important task. The development of the telegraph was a huge advance since the time necessary to communicate something was considerably shortened. It was then the turn of: the fax which enhanced the exchange of information. The problem was that these actions took a long time, they weren´t as accuracy as should be, and it wasn´t either a secure way of transmitting information. However, the new progress on remote technologies has changed the way people communicate themselves. Today, you can share words, pictures, or videos with somebody wherever both you are and whenever you want. Some people say that instant messaging is the text version of a phone call. The immediacy and effectiveness with which it is possible to obtain information using these tools have made several companies prefer to manage their relationships with partners, suppliers or colleagues using these new tools.
