Use maturity to diagnose capability, not prestige
A maturity model is useful when it describes how work actually happens. The connected-TV paper distinguishes four stages: Linear Dominant, Digital Extension, Converged Buying, and CTV-First Ecosystem. The stages are not a ranking of brand sophistication in every respect. They describe whether video is planned around channels or audiences, which metrics guide decisions, and how fully data and buying systems work across screens.
An organization may occupy different stages at once. A national brand team may run converged campaigns while regional teams still add streaming after the television buy. Measurement may be advanced even when creative operations are not. Score planning, audience data, buying, creative, measurement, and governance separately. The lowest capability is often the practical constraint on the next campaign.
Stages one and two remain channel-led
In the Linear Dominant stage, campaigns begin with broad demographic reach, television schedules, and panel-based metrics such as GRPs. Digital video is limited or absent. This can remain practical where connected-device access is constrained or audiences retain strong linear habits. The problem arises when the organization treats this context-specific approach as the universal default and cannot see viewers who have moved to streaming.
Digital Extension adds OTT or CTV as a supplement, often to reach younger or lighter-TV viewers or to add frequency. Planning still begins with linear, and reporting usually keeps television and digital results separate. This stage creates useful experience but also duplicates audiences and fragments accountability. The step forward is not merely a larger digital line item; it is a shared audience definition and an incremental-reach question.
Stage three unifies planning around the audience
Converged Buying breaks down the budget and measurement silos between broadcast, cable, CTV, and mobile OTT. Teams design the campaign across screens and use audience duplication, incremental reach, and frequency as common planning concepts. Each channel retains its strengths, but no buying team is allowed to define success solely by delivering its own impressions.
Reaching this stage requires more than a platform contract. The organization needs common audience taxonomies, compatible campaign naming, access to cross-screen measurement, clear data permissions, and a governance owner who can rebalance the mix. Creative also needs planned variants and sequencing. If those operating details are missing, the organization may claim convergence while still running separate campaigns under one presentation.
Stage four makes CTV central and outcomes operational
In the CTV-First Ecosystem, planning starts with an audience and desired outcome rather than a linear schedule. Programmatic buying operates at scale, identity resolution supports cross-device control, and optimization uses outcome, return, brand, and attention signals. CTV becomes the central bridge between premium television experience and digital accountability, while linear inventory can still be selected when it adds the right reach.
This stage also raises the standard for evidence. Real-time optimization is only as useful as the identity, attribution, supply quality, and experimental design beneath it. Automation cannot repair ambiguous objectives or invalid inventory. Mature teams therefore pair faster decisions with stronger controls, documented models, holdouts where feasible, and human review of changes that affect audience, risk, or brand experience.
Advance through the smallest meaningful capability step
Do not attempt to buy every stage-four technology at once. Choose the bottleneck that prevents a better decision today. A stage-one team might establish consistent digital reach reporting. A stage-two team might run one deduplicated reach study. A stage-three team might connect first-party audiences, automate frequency rules, or test incrementality. Each step should create evidence and a repeatable operating habit.
Review progress by capability and outcome, not by media share. Spending more on CTV does not prove maturity if planning, quality control, or measurement remains siloed. A quarterly assessment can record the current stage, the evidence supporting it, the next decision the team wants to improve, and the capability required. That turns transformation into a sequence of accountable changes.
| Stage | Planning center | Best next capability |
|---|---|---|
| Linear Dominant | Schedules and broad demographics | Consistent digital reach and quality reporting |
| Digital Extension | Linear plan plus streaming add-on | Shared audience definition and deduplicated reach |
| Converged Buying | Audience-led cross-screen plan | Cross-device frequency, incrementality, and governance |
| CTV-First Ecosystem | Audience and outcome optimization | Stronger experiments, identity controls, and supply assurance |
Decision implication
The four-stage maturity model gives teams a common language for change without pretending every market or business should move at the same speed. Diagnose the operating reality, identify the weakest enabling capability, and choose a step that improves a real decision. Maturity becomes credible when the new behavior can be repeated, measured, and governed.
