Nielsen Holdings plc unveiled a new syndicated service to measure subscription-based streaming content.

Eight networks and studios, including A+E Networks, Walt Disney Co.'s Disney-ABC, Lions Gate Entertainment Corp., Comcast Corp.'s NBCUniversal Media LLC and Time Warner Inc.'s Warner Bros., have signed up for the new Nielsen Subscription Video On Demand Content Ratings service, the company said Oct. 18.

Nielsen will use the new service to offer data comparable to what the company provides for linear television. Nielsen started measuring streaming content in 2014 via an opt-in service.

Meanwhile, Netflix Inc. said it will not be part of Nielsen's new service, saying "The data that Nielsen is reporting is not accurate, not even close, and does not reflect the viewing of these shows on Netflix," Variety reported, citing a company statement. Megan Clarken, president of Watch at Nielsen, reportedly said in an interview that the service was mainly aimed at Netflix, since it has 12,000 shows that have not been measured in the past.
