Till a decade or so in the past, TV viewership stats had been simply accessible via Nielsen scores, and the one trick was figuring out the distinction between a scores level and a share. However within the streaming period, TV viewership has develop into a guessing sport.
Many streaming platforms don’t share in-depth viewership information with the general public, leaving it to firms like Nielsen, Luminate, and Parrot Analytics to estimate viewers sizes for streaming TV sequence — for a price. And even then, streaming numbers for a given program can differ from one evaluation to a different.
“It’s extra chaotic than it’s ever been,” George Ivie, chief govt of the measurement watchdog Media Score Council, instructed The New York Occasions not too long ago.
Netflix launched its High 10 lineup in February 2020, however that function is barely a rating with no viewership numbers to be seen. The streamer took one other step towards scores transparency in December 2023, when it began releasing twice-a-year engagement studies exhibiting six-month viewership tallies for its choices. That’s progress, however streaming viewership information stays scarce.

When streamers are forthcoming, they tout their successes via numerous metrics. Right here’s among the most typical terminology on this evolving and sometimes complicated area of viewers measurement:
Hours/minutes considered: The period of time customers have spent watching a given movie or TV present. For hit TV reveals — particularly ones with many seasons out there for streaming — this quantity can soar into the tens of billions of minutes.
Views/streams: The variety of occasions a given movie or TV present has been streamed. Netflix’s newest engagement studies embody the variety of views in addition to the hours considered for every title.
Viewers: The quantity of people that watched a streaming title — or, no less than, the variety of accounts which have. Prime Video and Max usually use viewers as a metric for his or her public-facing viewership stats, per The New York Occasions.
Cross-platform viewers: The variety of viewers who watch a linear TV program stay, on DVR, on-demand, or via streaming. As The Hollywood Reporter factors out, a linear TV program’s streaming viewership numbers may be reverse-engineered if a TV community shares information about that program’s different viewership.
First X days: A qualifier for viewing statistics to point out a movie or TV present’s attain and engagement over the primary X variety of days that the title has been streaming — the primary three days, first seven days, first 25 days, first 28 days, and so forth.
Completion/retention price: The proportion of streaming viewers who end a movie or TV sequence, relative to the quantity who begin it. The analytics firm Digital I made up my mind in 2022 that Netflix TV reveals with completion charges under 50 p.c had been more likely to be canceled on the time, per What’s on Netflix.
Binge price: The proportion of streaming viewers who watch the episodes of TV sequence in fast succession, relative to all of that title’s viewers. In its viewership report for the second half of 2024, the analytics firm Samba TV shared that docuseries and crime dramas have greater binge charges — outlined in that report as the share of 31-day season finishers who binged that season within the first 5 days — than comedies or different dramas.
Starters, watchers, and completers: Categorizations Netflix has used for its viewers, as revealed in a July 2019 letter to a U.Ok. Parliament committee. “Starters” are households that watch two minutes of a movie or a TV episode, “watchers” are people who watch 70 p.c of a movie or a TV episode; and “completers” are people who watch 90 p.c of a movie or a season of a TV sequence.
