The document summarizes theories about the adoption of new communication technologies over time. It discusses Rogers' Diffusion of Innovations theory which identifies four main factors - innovation, communication channels, time, and social system - that influence the spread of new ideas. It also outlines Moore's innovation adoption curve, noting a difficult gap called "the chasm" between early adopters and the mainstream market. Finally, it defines critical mass theory as reaching enough adopters that the innovation's adoption becomes self-sustaining and promotes further growth.

3. Roger’s Diffusion of Innovations
According to Everett Roger,
the origins of the diffusion of innovations theory are very various.
He claims that there are four main elements that influence the spread of a new idea:
-innovation
-communication channels
-time
-social system
In blue, groups of consumers cross the market share,

4. Moore’s Innovation Adoption Rate
• Moore introduced what he called "the
chasm” to Roger’s concept.
• Moore noticed that Roger’s innovators and
early adaptors wouldn’t reach a full market
as well as early and late majority adaptors.
• This is the area that Moore calls the
chasm. Crossing the chasm seems to be a
critical and difficult task that any innovation
or innovative company must successfully
accomplish to reach wide market success.

6. Critical Mass Theory
• According to Roger, “critical mass is a sufficient number
of adopters of an innovation in a social system so that the
rate of adoption becomes self-sustaining and creates
further growth.”
