You crave more information? Good! A burning sense of curiosity is the sign of a healthy mind.
iTunesCharts.net monitors iTunes charts. It measures the performance of downloads over time. It means you can see how a certain download has performed in the chart throughout its lifetime, rather than just within the current chart.
Since iTunes only publishes the current chart, it's difficult to tell what that means. Is that just "today's chart"? Technically, yes, it's the chart RIGHT NOW. So what happens to old charts? Apple don't publish those. But we do!
This site was born out of an interest in how iTunes charts work. The podcast charts are particularly intriguing. If the charts are compiled based on a direct comparison on the number of downloads, then surely when a podcast channel published a new episode it would leap up the charts, right? Well, it doesn't appear to be that simple. The iTunes charts are intriguing things...
We collect the charts at the end of every day - we count that as the chart for the day. Since iTunes charts are updated more frequently than once a day, but it's difficult to be more accurate than that, and here's why:
This site aims to offer information on a larger scale than a single day. You can view a chart item's performance throughout its lifespan, which, we hope, is richer data than a single position at a single point in time.
If you've read this far you'll have realised that we don't really know how iTunes charts are complied. We possibly have more insight than most, but it remains a dark art. We should also make it clear, the team behind Apple iTunes have never disclosed how their charts work and could, in theory, completely change how the charts are compiled without notifying the public. What is certain is the charts reflect the buying patterns of iTunes customers - it makes commercial sense. The charts are a technique iTunes uses to put more product, in a structured way, in front of customers. The easiest way to sell stuff is to promote the most popular products.
We have... Plans. Ideas. Thoughts. Schemes. Dreams. Hopes.... (And some fears, naturally.) We're aware you do too. So, if you have a good idea (or an insightful criticism) you think we'd be interested in, then get in touch. Maybe your ideas are better than ours.
There's some stuff out there that makes for interesting reading:
