Google I/O 2013 was held at the Moscone Center, San Francisco. Announcements of updates for Android, Chrome OS, Google Chrome and other services were expected during the conference. The registration opened on March 13, 2013 at 7:00 AM PDT (GMT-7). It took only 49 minutes for all the $900 (or $300 for school students and faculty) tickets to get sold out, even with the added requirement that registrants must have both Google+ and Google Wallet accounts.
There was a fleet of remote-controlled blimps, equipped with camera, streaming a bird's-eye view inside Google I/O, live on www.ioairshow.com
