The change underscores the business news company’s determination to develop its new media platforms. Justin Smith became a digital superstar at Atlantic Media, best known for its respected monthly magazine The Atlantic. Through a series of online initiatives, the former publisher of The Week and head of corporate strategy for The Economist Group helped Atlantic Media connect with audiences who care about ideas as well as news — something that Bloomberg also is trying to do at Bloomberg BusinessWeek and its opinion/op-ed destination Bloomberg View. Smith made the Atlantic a forum for important voices including James Fallows and Andrew Sullivan, and used the magazine’s site as a launching pad for digital ventures including a business news and analysis destination, Quartz, and Defense One. At Bloomberg he’ll report to CEO Daniel Doctoroff and oversee television, print, radio, syndication, mobile, events and digital media properties. “I’ve long admired Bloomberg’s ambitious and entrepreneurial culture, and I look forward to contributing to the company’s march towards becoming the world’s most influential media company,” he says. Former NBC News and Sony Music chief Andy Lack, who ran the operation since 2008, becomes the unit’s chairman.
