NRC.nl - 'XTR branded content' - new ad network?

[KoffieNu]

Hello,

The app to read the Dutch paper NRC (https://play.google.com/store/apps/details?id=com.twipemobile.nrc) switched from a general ad network to what looks like to be their own.

Ads are now shown as 'XTR branded content' and on every article.

Regards,

Jan Huijsmans
