13. -16 Future challenges for Public Relation
Shannon & Weaver’sLinear Model (1949)
A one-way transmission model (sender → message → channel
→ receiver).
Noise — interference that distorts the message (e.g., bad
signal, unclear wording, audience bias).
Strength: Useful for technical communication (e.g., telephone,
radio).
Limitation: Assumes communication is linear, ignores feedback
and meaning-making.
PR Application: Press releases sent out to media — but no
guarantee of how they’ll be received or interpreted.
Osgood–Schramm Model (1954)
A circular model, showing communication as two-way and
interactive.
Feedback — both sender and receiver continuously
encode, decode, and interpret messages.
Strength: Recognizes communication as a process of
meaning-making, not just transmission.
Limitation: Doesn’t fully address power imbalances or
external influences (like media gatekeepers).
PR Application: Dialogue between a company and
stakeholders via Q&A forums or customer service.
Westley–McLean Model (1957)
Expands on two-way communication by adding
gatekeepers (e.g., journalists, editors).
Messages are filtered, shaped, or blocked before reaching
wider audiences.
Strength: Explains the role of media in shaping public
understanding.
Limitation: Still assumes a relatively passive audience.
PR Application: PR professionals must pitch stories through
journalists/editors, who decide what gets published.
One-Step and Two-StepFlow Models
(Katz & Lazarsfeld, 1955)
One-Step Flow: Media directly influence a passive audience.
Two-Step Flow: Media messages first reach opinion leaders (influential
individuals), who then interpret and pass them on to others.
Opinion leaders act as intermediaries, shaping how messages spread.
Strength: Recognizes the social influence of peers and leaders, not
just media.
Limitation: Underestimates audience’s active role in interpreting
messages (later models like Uses & Gratifications address this).
PR Application: Engaging influencers, community leaders, or experts
to amplify campaigns (e.g., doctors endorsing vaccines).

1. Press Agentry/ Publicity Model
One-way communication (organization → public).
Goal: Gain attention, create buzz, manipulate public
perception.
Tactics: Stunts, exaggerated claims, spin, sometimes misleading
information.
Ethics: Truth is optional—focus is on visibility, not accuracy.
Example: Early show business promoters, like P.T. Barnum hyping
circus acts; today, celebrity PR or viral publicity stunts.

2. Public InformationModel
One-way communication, but more ethical and factual.
Goal: Disseminate accurate, useful information to the public.
Tactics: Press releases, newsletters, official statements,
government briefings.
Ethics: Truth is central, but there’s minimal feedback or
dialogue.
Example: Public health campaigns, government agencies
providing factual updates (e.g., COVID-19 health advisories).
16.
3. Two-Way AsymmetricalModel
Two-way, but imbalanced (organization ↔ public, favoring
organization).
Goal: Persuade publics to accept the organization’s viewpoint,
using feedback mainly to refine persuasion.
Tactics: Surveys, focus groups, research-based campaigns to
shape audience attitudes.
Ethics: More manipulative—data is used to benefit the
organization, not necessarily the public.
Example: A company using market research to design
persuasive ads that increase product sales without considering
broader social impact.

4. Two-Way SymmetricalModel
Two-way, balanced communication (organization ↔ public).
Goal: Achieve mutual understanding and build long-term trust.
Tactics: Dialogue, negotiation, conflict resolution, collaboration
with stakeholders.
Ethics: Considered the most ethical model—organizations listen
and adapt based on public concerns.
Example: A company adjusting environmental practices after
dialogue with communities and NGOs
