argument that different media will compete with
each other for resources such as time and money.
Time Displacement: It suggests that the more
time that users spend on a new medium, the less
time they will spend on existing media.
Functional Displacement: A new medium
will displace the existing media if they can serve
similar function in a better or more effective way.

stop subscribing to the existing platform because
they feel they can be served by the new platform.

of getting TV transmitted over high-speed Internet

This chapter is part of a large project sup-
ported by the National Science Council in
Taiwan. This is the first study to focus on
IPTV users' viewing behavior in Taiwan, and
is also one of only a few to look into this
issue, regardless of the countries involved.
The results of the study contribute not only
to the scholarly literature but also to the
IPTV and cable TV industry.
