The process of interpersonal communication cannot be regarded as a phenomena which simply 'happens', but should be seen as a process which involves participants negotiating their role in this process, whether consciously or unconsciously.
Senders and receivers are of course vital in communication. In face-to-face communication the roles of the sender and receiver are not distinct as both parties communicate with each other, even if in very subtle ways such as through eye-contact (or lack of) and general body language. There are many other subtle ways that we communicate (perhaps even unintentionally) with others, for example the tone of our voice can give clues to our mood or emotional state, whilst hand signals or gestures can add to a spoken message.
In written communication the sender and receiver are more distinct. Until recent times, relatively few writers and publishers were very powerful when it came to communicating the written word. Today we can all write and publish our ideas on the Internet, which has led to an explosion of information and communication possibilities.
