India CTV reach reporting is inconsistent across publishers. JioHotstar reports "monthly active users." SonyLIV reports "subscribers." Zee5 reports "DAUs." DSP reports show "unique devices." Third-party vendors report "verified impressions." None of these metrics mean the same thing, and none is independently verified by a common currency body. Understanding exactly what each metric represents is the starting point for evaluating any India CTV campaign's performance claims.
Why India CTV reach numbers are confusing
Three structural reasons make India CTV reach reporting harder to interpret than display or mobile:
- No independent measurement currency: BARC India measures TV screen viewing but does not cover JioHotstar or YouTube — the two largest CTV platforms. There is no third party that independently audits CTV reach across all India publishers.
- Each publisher defines metrics differently: "Monthly active user" can mean "opened the app once" (JioHotstar's reported metric) or "watched 30+ minutes" (a more conservative definition some publishers use internally). Publishers rarely disclose their definitions proactively.
- Device ID coverage is partial: A significant portion of India CTV impressions (30–45%) have no resolvable device ID. These impressions still serve and are counted in impression totals, but can't be deduplicated — inflating reach numbers in publisher reports that don't distinguish ID-resolved vs anonymous impressions.
Four reach metrics publishers use
| Metric | What it measures | Inflation risk |
|---|---|---|
| Monthly Active Users (MAU) | Registered accounts with at least one app open event in a calendar month | High — includes mobile, tablet, TV; not CTV-specific |
| Daily Active Users (DAU) | Accounts with at least one session in a given day | High — same cross-device issue |
| Subscribers | Paid subscription accounts (does not mean active viewers) | Moderate — may include churned subscribers still within paid period |
| Unique Devices (campaign report) | Distinct device IDs that received at least one impression under the campaign | Moderate — excludes anonymous impressions; device ≠ viewer |
The metric that matters most for campaign evaluation is unique devices reached under the campaign, not the publisher's total MAU or DAU. A publisher quoting 150 million MAU is not saying your campaign reached 150 million people — they're citing their total app base across all devices and platforms.
How major India publishers report reach
JioHotstar: The merged platform (JioHotstar) has reported a combined MAU of 350–400 million users. This includes mobile, web, and CTV. CTV-specific reach is not publicly disclosed separately. Campaign reports from JioAds show unique device reach within the TV screen environment, which is what matters for CTV planning. The TV-specific MAU is estimated at 30–50 million active monthly viewers.
SonyLIV: Reports ~100 million registered users. Active paid subscribers are significantly lower — estimated 12–15 million in 2025. Campaign reach reports are device-level. SonyLIV's CTV inventory is primarily premium sports (IPL historically, cricket series) and drama originals, with TV-screen audience concentrated in metro SEC A/B.
Zee5: Reports ~85 million monthly active users across devices. Zee5's CTV audience is estimated at 8–12 million active monthly TV viewers. Regional language content is Zee5's strongest CTV pull. Campaign reports show impression-level delivery; unique device data is available on request.
YouTube CTV: YouTube does not separately publish India CTV MAU. Google reports overall India YouTube MAU of 450+ million (all devices). CTV-specific reach for YouTube on Indian TV screens is estimated at 25–40 million monthly based on Android TV and Chromecast deployment data.
What campaign reports actually show
A typical India CTV publisher campaign report includes:
- Impressions: Total ad serves. Does not equal reach.
- Unique devices: Distinct device IDs that received at least one impression. Excludes impressions with no device ID (~30–45% of total).
- Video completion rate (VCR): Percentage of ads played to completion. Includes co-viewers but is per-device.
- Average frequency: Impressions ÷ unique devices. Does not account for co-viewing or anonymous impressions.
- Reach by geography / platform / content: Available from some publishers (JioHotstar in particular); helps with post-campaign analysis.
What most India CTV campaign reports do not include: cross-publisher deduplication, person-level reach, co-viewer adjustment, or independent third-party verification of delivery.
How to normalise reach across publishers
For multi-publisher India CTV campaigns, buyers need a way to compare reach across publishers on a consistent basis. Practical approach:
- Use unique devices as the base metric — not MAU or subscriber counts from publisher collateral
- Divide impressions by average frequency to derive unique devices when unique device data is not directly available
- Apply co-viewing multiplier to estimate person-reach — but be transparent about the assumption
- Add a device ID coverage factor: if 35% of impressions are anonymous (no ID), true unique devices may be 15–20% higher than the ID-based number suggests (assuming similar reach patterns in anonymous inventory)
- Do not add unique device counts across publishers without deduplication: viewers of JioHotstar CTV and Zee5 CTV overlap; double-counting inflates total reach by an estimated 20–35% for multi-publisher campaigns targeting similar audiences
