Jim Dalrymple of The Loop recently spoke with Apple and, surprisingly, the corporate unfolded to him concerning the success of its Apple Stores. In line with a blog post at the Loop, Apple Stores have seen 300 million visitors worldwide because the the start of the fiscal year 2012 (October 2011). Dalrymple continues:

There can be an attractive data point from Apple’s retail Genius Bar. Consistent with the corporate, 50,000 people get serviced at a Genius Bar around the globe, day-after-day. That’s loads of appointments.

A lot indeed. And that kind of in-store traffic has translated to a ton of sales. Consistent with a brand new York Times story from this past June, Apple Stores make more cash per square foot of retail space than every other U.S. retailer. The days states that Apple Stores sold $16 billion worth of Apple products last year.

What’s the upshot of all this except to marvel on the unprecedented success and speculate on how long it’s going to last- Well, for one, expect long Apple Store lines come September, when Apple is predicted to sell an out of this world 250 million iPhone 5 devices.
