Benedict Evans wrote about app Store revenues.
- Google said it paid out $5bn to developers from Google IO in 2013 to Google IO in 2014 (a little over 13 months)
- Apple said it has paid out $20bn to developers in total by the end of the June 2014 quarter, and at WWDC June 2013 it gave a figure of $10bn paid to developers (at the June 2013 earnings call a month later it then said it had paid out $11bn). So in the last 12 months, it paid out roughly $10bn.
No surprise which platform app developers would want to go for.
