Two AOL employees were fired and its chief technology officer has left the company following a privacy breach in which the Internet search terms of more than 650,000 subscribers were publicly released. The researcher who released the data and that employee’s direct supervisor were fired, said one person familiar with the company’s decisions. The person, who spoke on condition of anonymity because release of personnel information was not authorized, would not say whether Govern’s departure was voluntary. AOL, a unit of Time Warner Inc., admitted earlier this month that it had made a mistake in releasing three months’ worth of search terms.
