Google I/O 2013 tickets go on sale - and sell out

Google I/O 2013 registration is officially open - and has officially sold out.

Tickets for the annual developer event were gone less than an hour after Google sent sales live at 14:00 GMT yesterday (13 March). But the company is offering a watch-it-live consolation prize for those who missed their chance to attend.

Keynotes and top sessions will stream on the Google Developers Live @ I/O site, available for viewing on PCs, smartphones, or tablets. All talks will also be recorded and available online afterward.

High price tags — $900 (£600) for the general public, $300 (£200) for academic students and faculty — barely slowed the rush of consumers. Still, the 2013 sell-out time didn't beat last year's 20 minute ticket exhaustion.

This year's developer conference will be held at the Moscone Center in San Francisco from 15-17 May. Google began sending save the dates to developers in December 2012, but offered little details about what to expect.

There are still no details about what sort of fun attendees can expect, but if it's anything like last year's proceedings, there will be lots to talk about.

At the 2012 extravaganza, Google showed off Android 4.1 Jelly Bean, Google Now, Google+ Events, 3D Google Earth imagery, a new YouTube app, and Chrome and Google Drive for iOS. There were also hardware advancements, including Google's first tablet - the Nexus 7 - and the flailing Nexus Q media hub.

The highlight of last year's show, however, was certainly the high-flying demonstration of Google Glass. Sergey Brin demonstrated the high-tech specs with a live video presentation from four skydivers sporting the glasses, who jumped out of a blimp and landed on the roof of the convention center. Google later allowed US-based attendees to reserve their own pair of Google Glasses for $1,500 (£1,000).
