The resignations of the top two executives at Graphix Zone Inc. in Irvine last week marked a significant milestone in the company's history. After all, the husband-wife team of Charles Cortright and Angela Aber had run Graphix Zone, a maker of multimedia CD-ROMs, since they founded the company in 1989.
But in a broader sense, they were just the latest to join the parade of top executives giving up their posts at high-tech companies in Orange County. So far this year, the CEO position has changed hands at more than half a dozen high-tech companies, including giants such as AST Research and Ingram Micro, as well as smaller firms such as Platinum Software and TouchStone Software.
Many of the departed executives had held their positions for a long time. Linwood A. Lacy had been chief executive of Ingram Micro in Santa Ana for about a decade before he resigned abruptly in a management dispute.
But experts say that in general, high-tech companies see more turnover in their executive suites than most other industries, mainly because the landscape of the high-tech industry can change so fast.
