Comcast’s Xfinity Stream app and web portal are being added to Nielsen’s digital ratings. Now Xfinity TV audiences watching on computers and mobile devices will be included in Nielsen Digital in TV Ratings and Digital Content Ratings.

The inclusion of Stream is an expansion of Comcast’s and Nielsen’s current agreement. Cable television viewership across Xfinity TV set-top boxes including the X1 platform is currently included in Nielsen's National and Local ratings.

"We're excited to continue to expand our relationship with Comcast to include measurement of Xfinity TV's digital audiences," said Peter Bradbury, executive vice president of national client solutions at Nielsen, in a statement. "Providing trusted, comparable metrics that help the industry monetize audiences across platforms is central to Nielsen's Total Audience mission and we're thrilled to work alongside clients like Comcast who are leaning into independent measurement."

"People are consuming content differently and across a variety of screens," said Marcien Jenckes, president of Comcast Cable Advertising, in a statement. "With this expanded relationship, our aim is to provide marketers with a more holistic view into how people are engaging with content and foster better exchanges between marketers and consumers."

The new agreement for Comcast and Nielsen comes after a few other recent deals between the company’s. Late in 2017 Comcast became the fourth U.S. pay TV operator to agree to sell its set-top data to Nielsen. Earlier this year, Comcast’s Freewheel and Nielsen agreed to expand measurement to over-the-top and set-top box video-on-demand ad inventory.

Nielsen’s Digital Content Ratings bring in data from streaming video, static web pages and mobile apps as viewed across devices including tablets, computers, mobile devices and connected TVs. The service includes data from major digital platforms including Facebook, Hulu and YouTube.
