Google hosted its annual developers conference this week, which it calls Google I/O. And for the first time since the start of the pandemic, attendees had the option to show up in person. The company announced software updates, new devices and, of course, details of improvements to the Android operating system, which runs on most of the world’s mobile phones. The event sets the tone for the other big tech conferences throughout the year. Marketplace’s Kimberly Adams speaks with Ian Sherr, an editor at large for CNET. He attended the conference virtually and said one of Google’s biggest reveals was a new wearable device.
