The iPod ecosystem continues to generate growth and profits for third party manufacturers.

Positive proof of the continued success of this market segment is clear, and a report today looks at the good fortune enjoyed by one, Jeff Grady and his company, Digital Lifestyle.

Inspired by Apple's iPod, Grady has now created a 150-piece product line that he's introducing this year. And within a year of launching his company, he has managed to reach revenues of $2 million already.

The company intends launching a speaker dock for iPods called the iBoom in the coming year.
