Nvidia founder and CEO Jensen Huang has resigned amid fallout over an affair with a suspected Chinese spy and allegations of other extramarital relationships, the company's board announced, KBS World reports. The board had been preparing to oust Huang after reports of two extramarital affairs, including one with a suspected Chinese spy, according to the Wall Street Journal, as cited by Korea Times. Chief Financial Officer Colette Kress, who joined the chipmaker in 2013, has been brought in as interim CEO, Korea Times reports. The leadership crisis has hit Nvidia's market value, with shares on track to shed more than $470 billion over two sessions, and a shareholder has sued Nvidia and Huang, accusing them of deceiving investors about the affair. Korean media coverage focuses on the business impact, with Business Korea calling it "the most serious leadership crisis in the company's history."
