16 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}. 16 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).

20 Types of electronic communication can be divided in written and recorded information. Recorded information, like audio or video data, is accessable only in a linear way by spooling and replay. Written information, on the other hand, can be accessed in arbitary sequence, detail and speed. 20 Types of electronic communication can be divided in written and recorded information.

22 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. 22 Another possible separation is to distinguished synchron and asynchron communication.

24 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. 24 Figure \ref{fig:comm-classification} shows a classification of communication technologies sorted by these two criteria.

26 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. 26 One might be surprised to find Instant \emph{Messaging} not in the group of \emph{message} communication.

28 Email is not limited to written information, at least since the advent of \NAME{MIME}, which allows to include multimedia content in textual email messages. Thus recorded information can be sent as subparts of emails. The same applies to Instant Messaging too, where file transfer is an additional subservice offered by most systems. In general recorded information can be transmitted in an encoded textual form. 28 Email is not limited to written information, at least since the advent of \NAME{MIME}, which allows to include multimedia content in textual email messages.

102 Life cycle analysis are common for products but also for technologies. This one here is for electronic communication technologies. The first dimensions regarded is the life time of the subject. It is segmented into the introduction, growth, mature, saturation, and decline phases. The second dimension can display sales, market share, importance, or similar values. The graph has always an S-line shape, with a slow start, a rapidly increasing first half, the highest level in the third quater, and a slowly declining end. Reaching the end of the life cycle means, the subject is inherited by its successor or the market situation changed thus making it oldfashioned. 100 Life cycle analysis are common for products but also for technologies.

104 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. 102 The current position on the life cycle of the introduced communication technologies is depicted in figure \ref{fig:comm-lifecycle}.

106 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. 104 Video messages and voicemail are technologies in the introduction phase.
