In Apple’s fiscal 2010 fourth quarter, the company’s revenue was $20.34 billion. This gave the Cupertino, California-based company $4.31 billion in profit. However, besides the dollar figures, consider this: 60 percent of Apple’s business today did not exist three years ago.

According to Horace Dediu of Asymco, the iPhone, iPod touch and iPad accounted for 60 percent of Apple’s sales. Each device debuted in 2007 or later.

In addition, take a close look at the chart below. It is a breakdown of what Apple sold going back to the last quarter of 2005. The spikes shown all occurred during the holiday season, except for the last one. The current quarter’s spike certainly bodes well for the 2010 holiday season for Apple.
