Other media companies participating in the trial include ABC, CBS, Fox, NBCUniversal, the CW, Turner, Viacom, Freeform, Hulu, GroupM, A+E Networks and AMC Networks.
The agreement includes satellite TV service Dish Network and virtual multichannnel video program distributor (vMVPDs) Sling TV.
Campaign Ratings will provide for person-level reach and co-viewing insights for linear national network audiences, OTT and addressable advertising.
Earlier this year, Dish joined with Comscore to measure Dish and Sling in what the companies say is the first cross-platform addressable advertising metric.
Among 120 million U.S. TV homes, estimates are that some 65 million of those households have technology to receive addressable advertising.
Advertisers can now see incremental viewing that Sling TV and Dish contribute -- over and above the linear TV viewing of their networks. The company says these insights will be incorporated into a “holistic” picture for advertisers.”
Dish say the deal to expand measurement will begin in the first half of 2019.
TV-video measurement competitor Nielsen has a similar product called Cross-Platform Campaign Ratings.
