The chip industry is in for major changes in the coming years, according to Broadcom Chairman and Chief Technical Officer Henry Samueli. In 1991, he co-founded the communications chip giant, which today brings in annual revenue of more than $8 billion from components for all manner of network, business and consumer products. At a pre-CES event in San Francisco earlier this week, Samueli visited from the company's Irvine, California, headquarters and sat down with IDG News Service to talk about devices, mobile networks and the uncertain future of silicon.
