After Google I/O sold out in 59 minutes, we gave ourselves a challenge: bring I/O 2011 to as many developers as we could, even those who didn't have tickets to Moscone Center. So for those of you not joining us in San Francisco or at one of our I/O Extended viewing parties, visit www.google.com/io on May 10-11 from the comforts of your own home, office or anywhere you have a reliable Internet connection for I/O Live.
