The Media Rating Council announced it has revoked accreditation for measurement services from Extreme Reach, Hulu and Protected Media, and denied accreditation for a service from DoubleVerify. It also granted accreditation for services from C3 Metrics, Hulu and Flashtalking.

The MRC said it revoked accreditation for all metrics reported for the Extreme Reach AdBridge platform, and for Protected Media’s display and video viewable ad impressions and related viewability metrics in desktop, mobile web, and mobile in-application environments in October.

The MRC said Protected Media chose to withdraw those metrics from audit, and that it remains accredited for other previously accredited services.

Accreditation was revoked for Hulu’s rich media completions in desktop and mobile in-application environments in November, and the MRC said Hulu chose to withdraw those metrics from the audit.

Accreditation was denied for DoubleVerify’s Vodafone custom video duration metrics, but its other previously accredited metrics remain accredited.

C3 Metrics was granted accreditation for served and viewable display ad impressions and related viewability metrics in desktop and mobile web environments.

Hulu was granted accreditation for display, video, and rich media served ad impressions and video completions in over-the-top (OTT) environments. 

Flashtalking was granted accreditation for display viewable ad impressions and related viewability metrics in mobile web environments.
