Google I/O got off to an eventful start thanks to keynote delays, the pre-release of news on Google’s websites before it was announced on stage and an epic skydiving stunt. Here is a quick run-down of day one by the numbers:
- 400 million active Android devices worldwide. Around this time last year, there were 100 million active Android devices.
- Google is activating 1 million Android devices daily.
- A million NFC-enabled devices are being activated every week.
