The Top Five Reasons Why iPhone Has Become Apple’s Most Prized Business

IPhone 4 New Pricing

Apple (NSDQ: AAPL) normally talks about a range of products during its annual Worldwide Developer Conference in San Francisco, but not this year — there was no announcements of new MacBooks and iPods were only mentioned in passing.

Instead, Steve Jobs was zeroed in on the new iPhone 4 and iPad, to deliver this underlying message: the iPhone — and other devices running the iOS — is their most prized division.

Here’s five reasons why:

1. Market potential: While the PC and laptop market has become saturated, there’s still plenty of wiggle room left in portable/connected devices. In the first 59 days the iPad was for sale, it was selling at a rate of one every three seconds. Apple’s Steve Jobs couldn’t have said it more clearly when wooing developers: Later this month, Apple will surpass 100 million iOS devices sold.

2. Advertising: On July 1, Apple is jumping into the mobile advertising business for the first time. In the past eight weeks, it has already secured $60 million worth of ads for the second-half of the year. While Apple claims it’s not in it for the money — but rather there to support the developer — it’s own piece of the pie is worth $24 million (40 percent). Not too shabby.

3. Apps: Jobs said it has now paid developers $1 billion for all the apps sold in the App Store. Based on the Apple’s industry-setting 70/30 split, Apple’s take away represents $430 million. It’s not gigantic, but it’s not trivial either. (Corrected: Thanks to everyone who pointed out the error. It’s $430 million, not $43 million).

4. Hardware: Just as with the iPod, all the ancillary businesses mentioned above are designed to juice hardware sales. And, the iPhone has something going for it that computers and music players don’t: Subsidies. Apple has found another company — namely AT&T (NYSE: T) and other international carriers — that are willing to discount the hardware, making their high-end devices more affordable to the masses. While end-users pay in the range of $199 per device, Apple reports the average selling price is closer to $620 each.

5. Revenues: The iPhone now represents Apple’s largest division by revenues. In the most recent quarter, iPhone and accessory revenues totaled $5.45 billion, compared to laptops and desktops which saw revenues of $3.76 billion. We don’t even know what iPad will do yet. Add all this up, and Apple became the largest tech company in the world by market capitalization, beating Microsoft (NSDQ: MSFT) last month.

We’ll be addressing some of these themes during our next conference, PaidContent2010 Mobile: Leveraging the Smartphone Boom, July 20 in New York City. You can find out more about the agenda and register at http://paidcontent.org/event/mobile2010/.
