TV watching has changed so much over recent years that Nielsen has now announced that they will include streaming services Hulu and YouTube TV in their ratings.
Nielsen has been measuring TV viewership since 1950 and is the the primary source of audience measurement information in the television industry around the world.
Nielsen’s President of Product Leadership Megan Clarken said: "This is the first time the biggest digital-first, TV streaming companies have come into the fold in terms of being included in TV ratings.
"With this inclusion, Nielsen measurement will provide media buyers and sellers with a more comprehensive and transparent view of audiences engaging with linear TV programming across digital devices."
Clarken added that the data about Hulu and YouTube TV will be incorporated into Nielsen’s C3/C7 numbers - these are used by TV ad-buyers and reflect viewership during a three and seven-day time window.
The change "is a major accomplishment in delivering Nielsen Total Audience to the marketplace," Clarked added. It’s "part of our commitment to provide trusted, independent measurement of the evolving modern media landscape."
On whether more streaming services will be added in the future, Clarken said: "The doors are open for those players who want to be lined up side-by-side and measured in a comparable way to traditional TV."
