Apple is still not providing any specific numbers either, though some analysts are estimating more than 700,000.

The company remastered its content to run at the optimal resolution for the iPhone's screen, which has a 16:9 aspect ratio when held horizontally, and a higher resolution than the video iPod. The new videos are available from the Podcasts section of the iTunes store, and include mixology instruction, dating advice and golfing tips.
