On this episode of CEO EXCHANGE, taped at the Kellogg School of Management at Northwestern University, we'll meet two CEOs who have navigated their well-established companies boldly into the future. Ed Zander found his calling when he transformed Motorola from a troubled electronics firm into the hottest mobile phone maker around. Allstate's Ed Liddy insured the well-being of his company by revamping an antiquated agent system while using new technology to boost efficiency. Two CEOs who made sure their venerable brands will be around for years to come.
