This week, more than 100,000 people from around the world — including staff from “Marketplace Tech” — are gathered in Las Vegas to talk tech at the annual Consumer Electronics Show. CES this year features more than 4,000 exhibitors, from small startups to tech giants like Amazon, Intel and Sony. There’s so much to see in so little time, so Marketplace’s Lily Jamali spoke with Gary Shapiro, president and CEO of the Consumer Technology Association, which runs CES, about what to watch for at this year’s event.
