For cross-service title and audience analysis, start with PeerLogix viewing intelligence.

Define the population, unit and time window, then use the measure that answers your business question. Household reach describes audience breadth; viewing activity, duration and derived demand scores address other parts of the decision.

PeerLogix has worked with streaming behavior since 2014. Our

[public title explorer](https://peerlogix.com/preview/)

,

[chart library](https://peerlogix.com/dashboard/)

and

[measurement definitions](https://peerlogix.com/methodology/)

show how observations become useful evidence. The process below helps you move from a headline number to an analysis your team can use.

## Connect the measure to a PeerLogix workflow

A content buyer needs to know which titles serve the audience and how they contribute to the catalog. A recommendation team needs relationships between titles. An investor needs a viewing series with a clear history and definition. PeerLogix connects those questions to cross-service evidence through licensed data and focused analysis.

Start with a result you can inspect. The

[catalog concentration page](https://peerlogix.com/charts/ti-rc-04/)

shows the leading titles' share of catalog title-demand score, with the underlying table and calculation. For a deeper title or audience question, take the same discipline into a scoped PeerLogix evaluation.

## Choose the unit that answers your question

Scroll sideways if needed to read every column.

The main measures and the questions they answer

| Measure | Useful question | Interpretation check |
| --- | --- | --- |
| Distinct reach | How many eligible entities watched? | People, households, accounts or devices; deduplication period |
| Viewing events or observations | How much recorded activity occurred? | What creates an event, and whether repeat activity is included |
| Minutes or hours | How much time was spent viewing? | Device scope, duration rules and treatment of simultaneous viewing |
| Share of an eligible panel | How common was viewing within the observed population? | Matching population, period and eligibility rules |
| Demand or momentum index | How does a title compare under the published formula? | Inputs, baseline, weights, normalization and whether the scale changes |
| Modeled population estimate | What might the result imply for a broader population? | Projection method, validation, assumptions and uncertainty |

Reach is useful when audience breadth matters. Time spent can describe depth of consumption. A title with fewer households may produce more total viewing time if those households watch more episodes. Neither measure alone identifies how much people liked the title or whether it caused a subscription.

For example, Nielsen's

[public Streaming Top 10](https://www.nielsen.com/data-center/top-ten/)

uses minutes viewed by U.S. persons aged two and older. PeerLogix public title views can report observed panel households. Read each source's population and device definition before trying to align the rankings.

## Define the audience population

Specify who can enter the measure. For a panel, record the eligible households and how eligibility is determined in each period. For first-party product data, identify the accounts, devices or people represented and the events the product can observe. A broad company-wide coverage statement cannot replace this definition.

A household may contain several people with different tastes. A device may be shared. An account may be used in more than one setting. Person-level claims require a method that supports them. Keep the entity label attached to the result in charts, exports and written summaries.

Population change can affect trends. If a source begins covering more households, raw title counts can rise even when the share watching falls. A compatible share-of-panel calculation helps separate these effects. It still describes the observed panel unless the source provides and validates a broader projection.

Small coverage also affects interpretation. An apparently large percentage change can start from very few observations. Ask for the source's suppression, quality and uncertainty guidance. Avoid presenting a finely ranked list of markets when the evidence cannot support those distinctions.

## Use the right time window and deduplication

Record the measurement window separately from the publication date. Compare seven days with seven days, and consider whether the question calls for calendar weeks or the same number of days since release. A midweek premiere has less time to accumulate activity in a calendar-week table.

Define repeat viewing. One household watching on five days may count once in weekly reach and five times across daily reach counts. To produce weekly unique reach, deduplicate the eligible household identities across the whole week or obtain a measure already computed at that grain.

The same issue appears across titles. Adding the reach of ten shows can count a household several times. A platform-level unique audience requires deduplication across the relevant title set and period. If you only have title-level aggregates, label the sum honestly and choose a question that the available measure can answer.

Illustrative measurement example

### A broader audience can spend less total time

Within the same eligible population and week, Title A reaches 1,000 households, each averaging 60 minutes. Title B reaches 2,000 households, each averaging 10 minutes.

Title A: 1,000 × 60 = 60,000 household-minutes

Title B: 2,000 × 10 = 20,000 household-minutes

Title B has twice the household reach. Title A has three times the household-minutes in this example. An acquisition decision about audience breadth and a programming decision about time spent could reasonably emphasize different results. These invented values illustrate units; they are not a PeerLogix dataset or a national estimate.

## Separate title viewing from platform attribution

A title may be available from several services, and its catalog membership can change by country and date. There are several distinct relationships: where it is available, which company owns it, which service originated it and where an observed viewing event occurred. Keep those columns separate.

If a chart allocates a title's demand to services that list it, the result is a catalog association under that formula. It is not automatically a measurement of plays supplied by each service. Ask how overlapping catalogs are handled and whether exclusivity is defined for the relevant market and date.

For commercial analysis, this distinction matters when a licensed hit moves between services or when a studio's title succeeds on another platform. The audience signal and the revenue beneficiary can differ. Combine the evidence with the rights and commercial information needed for the decision.

## Interpret an index in its own units

A score of 100 can mean the leading title has been set to 100, a baseline equals 100 or a different formula is being used. Read the scale before converting scores into an audience statement. A relative index can change because the title changes, the comparison set changes or the leader changes.

The

[PeerLogix Anime Pulse page](https://peerlogix.com/charts/ti-an-01/)

explains a relative ranking. The

[catalog concentration page](https://peerlogix.com/charts/ti-rc-04/)

examines how title demand is distributed within a catalog. Both are useful questions, but neither should be described as a direct national audience count.

Broader demand measures can include signals of interest beyond viewing. Use the

[viewership and demand comparison](https://peerlogix.com/compare/streaming-viewership-vs-demand-data/)

when deciding whether the task concerns observed behavior, attention or both. The word “demand” alone does not identify a formula.

## Compare markets and periods fairly

Align the eligible populations, title definitions and time windows before comparing. Check local availability, language, release timing and catalog changes. Normalize by a compatible denominator where the question calls for it, and report raw counts alongside the normalized measure when useful.

For country analysis, a larger observed count may simply come from a larger panel. The

[country comparison guide](https://peerlogix.com/guides/streaming-audiences-by-country/)

walks through a practical example. Avoid treating share of a provider's observed activity as national streaming market share.

Keep a record of source and method changes. A historical series rebuilt with revised mappings can differ from the version available at an earlier decision date. For a retrospective forecast test, use the information that was available then and document later corrections separately.

## Turn the measure into a business decision

Viewing evidence can help identify audience fit, catalog concentration, geographic interest and a pattern worth investigating. The next step depends on the question. A licensing team adds rights and costs. An advertising team confirms reachable audiences and delivery. An investor tests the relationship to company outcomes with appropriate validation.

Connect viewing to the business outcome using the appropriate account or financial evidence. For example, a retention study pairs viewing patterns with confirmed account outcomes. That gives the team a testable explanation for why the audience signal matters.
