today, because larger phone companies were slow to adopt VoIP capabilities, they're facing a rash of new, unexpected VoIP competitors,all of which have slashed prices and taken market share using high-speed Internet service. For example, COMCAST, a cable-TV provider that also offers high-speed Internet service, gains ten phone subscribers-at the expense of phone companies like Verizon and AT&T-for every cable TV subscriber that it loses. Likewise, VoIP is threatening the phone companies' wireless services, which now account for most of their profits. Scott Mesch, of Boulder, Colorado, used to pay 3.50 a minute to call relatives in Australia. Now he uses the TruPhone Internet application on his iPhone for just a few cents a minute. Says Mesch, "A lot of times I didn't even think of using my cell phone to make calls out of the country. now I don't hesitate ... it's no different from any other local call.
