Under some pressure to show that it's monetizing mobile, yesterday on its earnings call, Google announced a new "mobile run rate" of $8 billion. That compares with a run rate of $2.5 billion a year ago. The numbers aren't a direct comparison; Google threw everything into the $8 billion figure (ads, Google Play, app sales).
Here's what CEO Larry Page said in announcing the new run-rate number yesterday:
This time last year, I announced that our run rate from mobile advertising hit $2.5 billion . . . But now, we’ve built up additional mobile revenue from users paying for content and apps in Google Play . . . I can announce our new run rate for mobile is now over $8 billion. That’s quite a business.
CFO Patrick Pichette added a small amount of additional clarity:
The new [mobile] run rate is different from the one we gave you a year ago. And more specifically, last year, it included only our gross revenue from mobile ads, but this year, in this number we also added the gross revenue from the mobile sales of Google Play content. And finally, it also includes the consumer spending on the Play apps . . .
[O]f the three categories I gave you, ads continues to be the bulk of it, the vast majority of it. And then on the case of the Google Play, it’s important to note from a modeling perspective that everything’s that’s content, that is whether a book, a movie content is actually booked on our books on a gross basis . . . Everything that is tied to apps is booked on a net basis, but it’s still a huge kind of number in all cases.
Pichette said the "vast majority" of the $8 billion in revenue was comprised of mobile ads. Trying to estimate what percentage of this figure is ads with greater precision than "vast majority" is a bit tricky.
Google is counting content sales on a gross basis and app sales on a net basis (30% of the total). Despite Android's larger footprint than iOS, Google Play makes less money than the iTunes App Store.
In March, Flurry said that revenues in the Google Play market were 23% of the App Store. However this was limited to app sales and not content (if I'm reading it correctly). Google includes content sales (movie rentals/sales, book sales) on a gross basis.
Apple makes roughly $4 billion annually on App Store sales according to financial analyst estimates. Twenty three percent of that would be $920 million. If we assume that Google Play app sales have increased since Q1 Google night now be seeing a $1 to $1.5 billion app sales run rate on a global basis.
It's harder to estimate gross content sales; I haven't seen any estimates of Google content sales at all. Google's content sales are nothing like Amazon's. However, let's be extremely generous and say that it's $2 billion (gross) on an annualized basis.
Using these extremely loose estimates, $5 to $6 billion of the $8 billion run rate would be attributable to ad sales and $3 to $3.5 billion to content and app sales. Pichette's language "vast majority" to me implies something around 70% to 75% (or more) of the $8 billion is ad revenue. That would be right between $5 and $6 billion.
