Unfortunately, it's not that easy. Apple doesn't report "music revenues" but only "Other Music Related Products + Services". That includes "iTunes Store sales, iPod services, and revenues from Apple and third-party iPod accessories". In Q309, Apple reported about $950m revenue for that category. At the same time, more than 1b songs were downloaded from the iTunes store.
Source? I have to admit I didn't follow the iTunes Music section lately, so I was pleasantly surprised that their sales have picked up again recently. Didn't know that, thanks for the heads-up.
But I can only find precise announcements from Apple for 2 milestones: 5 billion songs in June 2008 and 8 billion songs in July 2009. Plus some fuzzy announcement of "over 6 billion songs" at Macworld January 2009. Did they announce 7 billion at some time this spring? For now I would go with the 5 billion and 8 billion milestones, which tell me that 3 billion songs were sold in the last 13 months, or 2.7 billion per year. Revenue for the "Music++" category was $3.85 billion between July 2008 and June 2009. The 2.7 billion songs fit snugly.
They announced 1.5b on the very day the 3GS was announced.
Not true. 1.5 billion were announced 5 weeks later, on 14 July. So far all AppStore milestones were announced in a dedicated fashion, so I would call them accurate.
Wait till an entire year has passed. 200m Apps were downloaded in one month alone around Christmas 08/09.
...actually in 42 days between 12 Dec and 16 Jan, which would be 142 million per month. Since then the AppStore has trended up towards 150, 160, 180 million per month, based on the milestone announcements.
It will probably be more something around 800m this/next year.
That depends on Apple's hardware releases and price points. So far I can't see anything of that magnitude. But as you said, we should wait how it develops. Unfortunately, that's not what AdMob did.
Of course it is in line with iPhone/touch sales! But calling the market "stabilizing" when iPhone sales explode at the same time is truly an achievement... I don't know how well the iPod touch is doing at the moment, but new models on 9/9 surely won't hurt sales.
True, downloads are growing fast, but stabilizing on a per user basis (attach rate). I'm counting 4 to 5 downloads per month per device, and this rate has been steady since December.
How exactly did you calculate those numbers? Can you base them on something more solid than wild guesses. I agree that 200m is unlikely, but not that far away from reality.
I. $0.25 per download (based on Steve Job's comment of $0.50 per download back in August'08)
II. 200 million downloads per month (based on the last 2 milestones announced, plus a little)
= $50 million in revenue per month (or $10 to $100 million).
I would say it's an informed guess, that's why I'm giving a wide margin. What's AdMob's margin of error?
You are very quick at ruling out the possibility that people download a lot more than what is in the Top10 or even Top100 of paid apps.
I'm not calculating with the the Top 100 at all, I'm merely looking at the totals. It so happens that bghoward's and other developers' accounts match with what I've listed here.
All I'm saying is that this survey bears far more significance than sales numbers of a single app and unless someone else comes up with better numbers, it's the best we got.
I'm surprised you're still saying that. Did you read in what cheap fashion the survey was conducted?
- Participants were randomnly invited by banner ads.
- Then AdMob tried to weigh them by demographics to make it a little more representative.
- No telephone or personal 1-to-1 interviews. Online only.
- Participants were able to claim how many apps they downloaded how and much they spent without any proof, just from their own memory and vanity. AdMob did not have any genuine sales data and did not ask to see receipts from the iTunes Store.
- The report contains no qualifications or margins of error.
Bottom line: This is not a serious study by any standard. On the other hand, there are dozens of accounts from developers out there who told us how much they've sold on each of the AppStore chart positions and there are Apple's milestone announcement. These are factual results, not estimates, so they are the best we've got.
