Three important trends in telecommunications have re-
ceived media attention for their potentially wide-ranging
impacts. The first is increasing competition among tele-
phone service providers, spurred in the United States by the
Telecommunications Act of 1996. The second is the tech-
nological convergence between telephony and the Internet.
The third is the ever-increasing number of mobile devices
and users.
