Google I/O 2016: from Allo to Daydream, what you need to know

Google I/O is the biggest date in the firm's calendar: it's the conference where it gets everyone together in one big room (actually, this year it was a tent) in California to reveal all the cool stuff it has been working on. This year was more focused than most. It's the first I/O since the company restructured itself into Alphabet, hiving off the wilder projects such as Google Glass, self-driving cars and life-extension research into other subsidiaries. Gone are the days of livestreaming a parachute jumper wearing Google Glass from the I/O stage. But that doesn't mean the company wasn't trying to impress with more down-to-earth revelations.
