Faxing is growing in popularity
The persistence of faxing — and the people who send faxes — is in part because the fax industry has adapted to accommodate new technologies. Fax machines still dominate, but both surveys suggested users were shifting to computer-based services, such as fax servers that let users send and receive faxes as electronic documents. These new systems can transmit faxes over telephone lines or the Internet, depending on the recipient, handling paper and electronic documents equally easily.
