Revenue from Google properties rose to 27 billion from about $22 billion in the year-ago quarter. Revenue from network members rose 12.4% to 5.6 billion, compared with a year ago.
YouTube's ad revenue will grow nearly 20% this year to $11.38 billion worldwide. YouTube's share of Google's net ad revenue worldwide remains at 11%. In the U.S., YouTube leads in OTT video services, with 197 million users this year.
That represents a 96.2% share of OTT video users in the U.S., according to eMarketer.
Google’s "other" revenue -- about $6.48 billion -- includes money from cloud partnerships, Nest, Google Play and more. It also includes Verily and Waymo, health and driverless cars, respectively.
