Diffusion Theory in the Internet Environment
• Hard to define a social system
“The Internet might be changing the role of spatial
distance in who talks to whom about a new idea.”
• Internet communication as both
mass and interpersonal communication
“The Internet allows people to reach many people in a
one to many process, but e-mail messages are like
interpersonal communication.”
•~ Everett M. Rogers, 2003~
Four Key Components in Diffusion Theory
• Adopter Categories:
innovators, early adopters, early majority,
late majority, and laggards
• Mass Communication Channels:
newspapers, network news, local news,
cable news, and online news
• Cosmopolitan Experience:
access non-US sources, communicate with
people outside of US, and travel to many
countries
• Gender:
Is the Internet gendered?

Hypotheses & Research Question
H1: Earlier adopters of Internet news are more
likely than later adopters to be regular users of
all news channels.
H2: Earlier adopters are more cosmopolitan than
later adopters.
H3: Male are more likely than females to be earlier
adopters of Internet news.
RQ: What is the relationship among gender,
Internet news adoption, and Internet news
reading?

Results
•
College innovators and early adopters of Internet
news were cosmopolitan males who read online
news and watched cable and local TV news on a
regular basis.
•
Gender was not only a strong predictor of how
long students adopted Internet news but also an
antecedent variable to the relationship between
Internet news adoption and Internet news reading.
Contributions
•
Matched Rogers’ adopter categories with college
students’ Internet news adoption.
•
Constructed a scale to measure “cosmopoliteness”
and found earlier adopters were more
cosmopolitan.
•
Digital Divide in New Forms:
Experience Divide
Information/Source Divide
Gender Divide (conditioned by experience)
