The service is based on its Total Home Panel, a research platform that measures consumer behaviour across home network-connected devices covering 12,500 households and 150,000 active devices per month.

Although OTT content is growing and services such as Netflix have gained popularity, it has been difficult to measure activity streamed through TV-connected devices.

Mike Rich, comScore vice-president of emerging products, said: “With very limited insight into viewing behaviour across providers, the OTT market has largely been a black box.

As more TV viewers look beyond traditional content sources, it’s more important than ever for networks, content producers, device manufacturers and others in the ecosystem to understand this growing segment of cross-platform viewing.”

ComScore OTT Intelligence gives subscribers a single-source view of dozens of OTT content providers including Netflix, Amazon, Hulu, and YouTube. Reported measures include household reach, audience size and demographics.
