Which of the following factors affect mediated persuasion?

The factors that affect mediated persuasion here are media differences (3), audience fragmentation (4) and message characteristics (5).

Media differences (3) matter because each medium carries and frames a persuasive message in its own way.

Audience fragmentation (4) matters because a split, scattered audience is harder to reach with one persuasive appeal.

Message characteristics (5) matter because wording, tone and structure shape how convincing a message is, while extended media reach (1) and round-the-clock communication (2) describe media availability rather than what drives persuasion itself.

Persuasion depends on how message, medium and audience meet.

Matching the message to a fragmented audience is a core challenge.
