An anonymous reader shares a report: People now watch so many programs at so many different times in so many different ways -- with an antenna, on cable, in an app or from a website, as well as live, recorded or on demand -- that it is increasingly challenging for the industry to agree on the best way to measure viewership. In some cases, media executives and advertisers are even uncertain whether a competitor's show is a hit or something well short of that. The scramble to sort out a suitable solution began nearly a decade ago, as Netflix rose to prominence. It has only intensified since. "It is more chaotic than it's ever been," said George Ivie, the chief executive of the Media Rating Council, a leading industry measurement watchdog. For decades, there was no dispute -- Nielsen's measurement was the only game in town. But things started to go sideways after the emergence of streaming services like Netflix, Hulu and Amazon Prime Video. Nielsen had no ability -- at least at first -- to measure how many people clicked play on those apps. The streamers, of course, knew exactly how many people were watching on their own service but they either selectively disclosed some data or did not bother releasing it at all. Over the past two years, as nearly all the major streaming services have introduced advertising, they have released more data. But the data they release makes apples-to-apples comparisons difficult. Netflix discloses what it calls "hours viewed" and "views" for its shows. Prime Video and Max prefer to describe how many million "viewers" watched a hit of their choosing. The disclosures can be helpful to compare one show with another on the same streaming service. Yet those figures, too, can lead to disagreements.Read more of this story at Slashdot.
