Yesterday’s Apple event was music to the ears of statistics fans. In his usual fashion, Steve Jobs reeled off a long list of millions and billions related to the consumption of Apple products and services. For example, in the time it will take to read this sentence, more than 200 apps will have been downloaded from Apple’s App Store.

Of course, there was a slew of new product announcements as well. Traditionally, Apple’s September events have focused on the iPod (275 million sold to date), and yesterday was no exception. Apple introduced a complete refresh of its line of popular music players. In the “one more thing” department, Apple also unveiled a revamped Apple TV focused on streaming video, including the long-awaited addition of Netflix (nicely complementing the recent addition of the Netflix iPhone app).

But as exciting as these product updates are for music and video lovers, the key announcements revolved around the introduction of the Game Center social gaming platform, and Ping, a social network for iTunes users. These new platforms lay the groundwork for Apple to leverage the growing nexus of mobile, social, content and commerce.

In my just-released report, “Mobile Content: Games, Music and Video Take to the Cloud,” I cite a series of studies by Edison Research and Arbitron that suggest social networking is emerging as a bellwether for mobile content consumption, with frequent social network access leading to higher-than-average indices of gaming, listening to music and watching video on mobile devices.

In many ways, it makes perfect sense: music consumption has always been about sharing (favorite artists, songs, etc.). And while one may bemoan the demise of the mix tape, incorporating sharing mechanisms into the commerce platform and making them available on mobile is a logical move that strengthens the platform and makes it stickier. Social commerce is fast emerging as a key driver of sales, and content marketers benefit by enabling their audience to do some of their marketing for them. In the case of Ping, the platform could also emerge as an effective way for artists to market themselves as well.

Similarly, as gaming becomes a more social experience (e.g. more users playing interactive multiplayer games and using social features to share both games and results), social networks are likewise becoming more game-like, with users competing for status through check-ins.

Yes, social network fatigue is a danger (as is Ping’s current lack of Facebook and Twitter integration), and no, iTunes fans didn’t get the streaming version some had been hoping for, but the combination of mobile, social, content, commerce and cloud points the way to the future.
