crossmedia communication

For starters I would like to give you all my definition of crossmedia communication:

Crossmedia communication is communication where the storyline will direct the receiver from one medium to the next. This makes it possible to transform from one-dimensional communication (sender -> receiver) to multi-dimensional communication (senders <-> receivers. Furthermore I believe that good crossmedia communication will enhance the value of communication in two ways:

1. Financial profits through equal or decreasing costs for the same communication effects with single medium communication. It is possible to shift costs for communicating from the sender to the receiver, if the story is attractive enough for the receiver to want to interact with it (at extra cost)

2. The level and depth of involvement will be more personal and therefore more relevant and powerful.
