Google I/O 2014 registration was originally slated to begin last week, but in a post on Google+, the company announced that it was pushing the registration window back a week in order to further perfect the registration process. Registration for Google I/O 2014 will officially open tomorrow, April 15th at 4:00 PM PDT and will run through April 18th at 2:00 PM PDT.
While in past years Google has run I/O registration on a first come, first serve basis, it will be adopting a new strategy this time around. This year, people interested in attending can sign up during the 4 day window and once the window closes, Google will randomly select who will get the opportunity to purchase an actual ticket. This is very similar to the process Apple used for WWDC signups this year, as well.
