Tickets for Google's upcoming I/O developer conference were sold out in less than an hour after being made available for sale.
According to a series of tweets made by Google VP of Engineering Vic Gundotra, the tickets were sold out 59 minutes after registration opened.
The speed marks a huge increase from previous years, when tickets could still be available many weeks after registration opened. In 2009, tickets for the conference took 90 days to sell out and those for the 2010 event took around 50 days.
In a post on the official Google blog, the company had explained that tickets were available at an Early Bird rate of $450, expected to last through until 16 April, when the price would jump to $550. Faculty and students could register at the Academia rate of $150.
Google I/O will take place on 10 and 11 May at the Moscone Center in San Francisco. Around 5,500 people are expected to attend.
