Apple Stores generated nearly $10 Billion in revenue in 2010

"Ten years later, there are 324 Apple Stores: 233 in the U.S., and 91 international locations. In terms of foot traffic, Apple saw its billionth retail visitor last month, with 71 million in the last quarter alone, up 51 percent year over year. The increasing number of visitors can be ascribed not only to the popularity of Apple products, but location of stores. In the U.S., the goal has always been to have 85 percent of the population within driving distance of an Apple Store, which has often meaning paying a premium for retail space. Bu it’s been a strategy that’s paid off.
For fiscal year 2010, just under $10 billion in sales came from Apple Stores. Last quarter, revenue from Apple retail was $3.19 billion, up 90 percent year over year. That means Apple Stores accounted for 13 percent of the company’s revenue, an impressive figure that puts them far ahead of competitors like Best Buy when measured by metrics like sales per square foot.
Last quarter, Apple sold 797,000 Macs in Apple Stores, up 32 percent year over year. One of every five Macs sold now comes from an Apple Store, but even more important is who is buying them. Going back at least five years, about half of those buying Macs in Apple Stores are new to the platform."
