The mechanical model of mass communication is characterised by which of the following?

The mechanical model of mass communication is marked by one-way flow, a one-to-many reach and possible anonymity.

Statement 2, one-way flow, fits because messages travel from the source to the mass without simultaneous return.

Statement 3, from one to many, fits because a single source addresses a vast dispersed audience.

Statement 4, can be anonymous, fits because senders and receivers remain personally unknown to each other.

Multiple-way flow belongs to interactive and transactional models, not the mechanical one.

An active audience that co-creates meaning contradicts the passive receiver of this model.

This picture derives from the Shannon and Weaver engineering line.
