2 Communication gets faster in general. Slow mediums as letters get substituted by electronic mail, which is delivered within seconds. Also communication becomes more transmitted through digital channels. This can be seen at the telephone which's information is now more and more transported in bits over the internet link. Also telefaxes are succeeded by email or are transported within email. Instant messaging can be seen as the written couterpart to the telephone; not to substitute it completely, but to be used if it is more useful for the information to transmit.

4 Many of the digital communication methods gained success by beeing cheaper than their counterparts. One example here is instant messaging in contrast to the telephone. As phoning costs fell, it became more popular again. The last years showed, that communication cost degreased dropped generally, caused by the transport through digital channels. And nothing to see, that would make them rise again.

10 Regarding the variety of communication methods shows a change, too. Communication systems are more easy to establish today, so more get established. This leads to more methods a person uses. But not only in the amount, also in parallel. For example when two people talk to each other on the phone, one might send a \NAME{URI}\footnote{Uniform Resource Identifier} by email meanwhile, because oral communication is not well suited to exchange such data. Another example for in parallel used communication channels is video chatting. Ony typically sees the other person, talks to it, and additionally has a instant messaging facility for exchanging written information.

12 Parallel usage of different kinds of communication channels will be important in future. The most common combinations are one for spoken and one for written information. But one for dialogs and one for sending documents will be important too.
