The Seattle Times: Business & Technology: How "search" is redefining the Web ? and our lives: "Three quarters of U.S. Internet users, or about 120 million people, have used engines, searching an average of 38 times a month. As the technology has taken off, its influence has rippled through other industries.

Timely snapshot and historical summary.
