Tickets for Apple's annual Worldwide Developer's Conference (WWDC) vaporized once again in record time, selling out in less than two minutes.

Tickets for this year's WWDC went on sale at 10 a.m. Pacific Time/ 1 p.m. Eastern Time and, as expected, they sold like hot cakes despite the hefty $1,600 price tag. In 2010 the tickets sold out in eight days, in 2011 in less than 12 hours, in 2012 in just two hours, and this year in just under two minutes.

For the sake of comparison, the tickets for Apple's WWDC sold out 95 percent faster than Google's annual I/O developer conference, which sold out in 49 minutes. Back in 2012 Google I/O tickets sold out in 30 minutes, but this year it took longer because a large percentage of users were unable to complete the check-out process early on.

This year's WWDC will be the first time Apple makes conference video available during the conference itself, not after the event, as it previously did. This should ease some of the disappointment for those who weren't fast enough to snag a ticket and actually attend the conference.

The faster-than-usual sell-out is most likely due to proper announcements. This year marked the first time that Apple gave advance notice to inform users when tickets would go on sale.

The fact that WWDC tickets sport quite a steep price tag and tickets were limited to just one per individual and five per organization, tracked by individual Apple ID, makes this record even more impressive. Considering that Apple's late CEO Steve Jobs said at one point that over 5,000 people attended the show, it's possible that Apple just made roughly $8 million in gross revenue from the event in just 90 seconds or so.

On the other hand, Apple's developer economy is now a full-grown industry. The Cupertino tech giant paid out a total of $9 billion to developers, at a rate of roughly $1 billion per quarter. Both the iPhone and iPad continue to grow in popularity and iOS as a platform is increasingly gaining more global users. All things considered, demand for WWDC tickets is getting higher as well.
