What will be the correct example of communication professionals ?

Communication professionals are the people who practise the craft, namely journalists, advertisers and news-readers.

These are trained individuals who gather, shape and deliver messages for a living.

Newspaper and television are the carriers of messages, that is media rather than professionals.

A conference, a meeting or a procession describe communication events or gatherings, not the practitioners.

Phones and email are technical channels and tools, again not the human professionals.

Public relations officers and editors also fall within this same class of communication professionals.
