According to reports, even though the registration is officially open for Google's annual developer conference - the 2013 Google I/O event, which is scheduled to be held at the Moscone Center in San Francisco from May 15 to May 17 -, the tickets for the event have sold out.

Within barely 50 minutes of the commencement of the sale of Google I/O tickets at 7 a. m. PT (10 a. m. ET) on Wednesday, the registration page started showing the message that the event had "sold out."

Along with the "sold out" message, the page also featured a note which said that the keynotes and top sessions of the event will stream on the Google Developers Live @ I/O site, and will be available on computer, phone, or tablet.

Despite the fact that the sell out time for the Google I/O event this year could not beat the 2012 sell out time of just about 20 minutes, there was hardly any slow down in the rush of consumers for the 2013 event; with the high price-tag of the tickets - $900 for the general public, $300 for academic students and faculty - being no deterrent at all for the consumers.

The annual Google I/O has always been a popular attraction for the developer community as well as the consumers because the event has essentially been the venue for Google's announcement of major releases of Android; and has also unfolded the opportunity for the attendees to check out the company's experimental products.
