Professor Keshav said that once a carrier invests in the centralized storage equipment — storing a terabyte now costs only $100 and is dropping — and the staff to maintain it, its costs are basically covered. “Operating costs are relatively insensitive to volume,” he said. “It doesn’t cost the carrier much more to transmit a hundred million messages than a million.”
UNTIL Mr. Kohl began his inquiries, the public had no reason to think of the text-messaging business as anything but an ordinary one, whose operational costs rose in tandem with message volume. The carriers had no reason to correct such an impression.
