Intel named Patrick Gelsinger, a vice president, to be chief technology officer, the first such appointment in the company's 33-year history. Mr. Gelsinger, 40, will coordinate long-term research on computing, networking and communications technologies. He will report to Craig Barrett, Intel's chief executive, the company said. Intel needs to expand its chip portfolio beyond personal computers into telecommunications and computer networking as sales weaken amid a slowing global economy and as consumers find fewer reasons to upgrade PC's.
