Google released its Q4 2014 earnings today, showing strong numbers all around, but on the earnings call we also got word on the strength of Google Play. Google CFO Patrick Pichette said today on the call that Google's "other revenues" segment grew by 19 percent year-over-year (6 percent quarter-over-quarter) to $1.95 billion, driven primarily by growth in Play Store sales.
"Other revenues" doesn't sound too important, but it actually makes up a full 11 percent of Google's revenues as of Q4, which is nothing to sneeze at. The growth came despite critical shortages of the Nexus 6, which Google confirmed earlier in the call.
The Play Store isn't going to become a substantial portion of Google's revenues any time soon, but it's clearly heading in the right direction.
