Joseph Lechleider, a Father of the DSL Internet Technology, Dies at 82 - NYTimes.com:
"Digital subscriber lines were not an immediate success. Early versions were not capable of video-on-demand services, the market the Bell companies originally wanted to enter. And when the Internet began to take off in the 1990s, most consumers went online using dial-up modems, which increased the demand for second phone lines in homes. That was a good business for the phone companies, and a familiar one.
Why opt for this new DSL technology? “There was considerable skepticism,” Mr. Lechleider said an interview with The Wall Street Journal in 2003. “There were people who didn’t want to deploy it. There were people who didn’t think it would work. Many of them weren’t sure there was a market for it.”
But as the web added more data-rich images, music and video, the demand for affordable, higher-speed communications services surged. And DSL technology afforded the phone companies a path to do that for years without having to undertake the costly alternative of installing fiber-optic cable into homes."
