As noted by 9to5Mac, Apple has introduced support for reader demographics and third-party advertisers for Apple News. News is a mobile app and news aggregator for iOS devices (and, I hope, someday for the Mac).
Publishers can now view reader demographics under the News Publisher Analytics section. The analytics provide insight into male and female readership and their age ranges for those that have read content within the News app on iOS 10.3, according to 9to5Mac.
What’s more, Apple News now supports new ad format sizes more inline with standard web ad sizes, the article adds. These include 300×250 and 728×90 sizes.
