     1.5  As globalization proceeds and long distance communication becomes more and more important. The future of electronic communication is bright.

     1.7 -Electronic communication includes the following technologies: electronic mail (email), instant messaging (\name{IM}), chats (e.g.\ \NAME{IRC}), short message service (\NAME{SMS}), voicemail, video messages, and Voice over \NAME{IP} (VoIP), as well as \NAME{GSM} and \NAME{UMTS}.

    1.14  Another possible separation is to distinguished synchron and asynchron communication. Syncron communication are direct dialogs with little delay. Telephone conversation is an example. Asynchron communication are one-way message systems; of course, dialogs are possible here as well, but not in the same direct fashion. These two groups can also be split by the time of data delivery. Synchron communication requires nearly real-time delivery, while for asynchron communication message delivery times of several seconds or even minutes are sufficent.

    1.16 -Figure \ref{fig:comm-classification} shows a classification of communication technologies sorted by these two criteria. Email and \NAME{SMS} are written and asynchron communication; \NAME{IM} and chats are written information too, but synchron. Recorded information are voicemail and video messages as examples for asynchron communication, and VoIP and \NAME{GSM}/\NAME{UMTS} as examples for synchron communication.

    1.19  One might be surprised to find Instant \emph{Messaging} not in the group of \emph{message} communication. Instant Messaging could be put in both groups because it allows asynchron communication additional to being a chat system. The reasons why it is sorted to dialog communication are its primary use for dialog communication and the very fast---instant---delivery time.

    1.52  The current position on the life cycle of the introduced communication technologies is depicted in figure \ref{fig:comm-lifecycle}. It is important to notice that there is no time line matching for all of them---some life cycles are shorter than others---the shape of the graph, however, is the same.

    1.54 -Video messages and voicemail are technologies in the introduction phase. Voice over \NAME{IP} and \NAME{UMTS} are heavily growing these days. Instant Messaging has reached maturation, but still growing. Email and \NAME{GSM} are examples for technologies in the saturation phase. Declining does none of the above mentioned; telefaxes would be an example for a declining technology.
