Apple official milestones

The data shown below reflect press release official milestones as published by Apple on their website.

At the last available reading, on 2006-02-23 iTunes had been 1032 days old, giving an average download rate of 969074 songs per day. By a simplistic logarithmic calculation, the number of downloads has doubled approximately 29 times, or about once every 34 days. Assuming Moore’s law holds, iTunes grows 1586% faster than digital storage capacity and microprocessor power.

We can try to formalize the data a little bit better. A simple linear regression to the second degree (using the least squares method) gives us the following trend:

The red line shows the best polynomial fit for the data, and we can see that if this growth continues, we expect iTunes to reach 2 billion downloads by February 2007.
