JioFiber is the single most important infrastructure driver of India's CTV growth. Reliance Jio's home broadband service has expanded reliable fibre internet into millions of Indian households that previously had no fixed broadband connection — and every JioFiber household is a potential CTV household. Understanding JioFiber's role is not just infrastructure knowledge: it shapes where India CTV is growing fastest, who the new CTV audiences are, and what data advantages Jio brings to CTV advertising targeting.
What JioFiber is
JioFiber is Reliance Jio's fibre-to-the-home (FTTH) broadband service, launched commercially in 2019 and expanded aggressively since. It offers home broadband plans with speeds from 30 Mbps to 1 Gbps and bundles streaming content access alongside connectivity. JioFiber subscribers get access to JioCinema (and in some plans, subscriptions to partner OTT platforms) bundled with their broadband plan.
Jio AirFiber, launched in 2023, extends Jio's fixed wireless broadband into buildings and areas where fibre laying is impractical. AirFiber further accelerates Jio's household broadband footprint beyond what physical fibre deployment alone could reach.
As of 2024–25, JioFiber has over 30 million home broadband subscribers, making it India's largest home broadband provider. The majority of JioFiber households have a smart TV or streaming device — Jio sometimes bundles JioFiber with a set-top box or streaming stick.
Why JioFiber matters for CTV advertising
It is expanding the CTV household base
Before JioFiber, reliable home broadband was concentrated in urban metros and was expensive. JioFiber brought affordable home broadband to tier-2 cities, smaller towns, and urban neighbourhoods that previously relied on mobile data for all internet access. Mobile data is inadequate for quality CTV streaming — it is intermittent, has data caps, and produces a poor viewing experience on a large screen. JioFiber's fixed broadband enables the consistent, high-bandwidth streaming that CTV requires.
The implication: JioFiber is the primary reason India's CTV household base is growing into tier-2 cities. New CTV households in cities like Jaipur, Nagpur, Bhopal, Coimbatore, and Vijayawada are disproportionately JioFiber households.
It creates a captive JioCinema audience
JioFiber plans bundle JioCinema access. When a household subscribes to JioFiber, JioCinema is the default streaming platform promoted through the setup process, the set-top box, and Jio's ecosystem. This creates a strong structural bias toward JioCinema viewing in JioFiber households — particularly for live sports.
It generates first-party household data
JioFiber is a household-level internet service. Reliance has verified address, household composition, and payment data for every JioFiber subscriber. Combined with JioCinema viewing data, MyJio app data, and Jio mobile data (many JioFiber households also use Jio mobile), Reliance's data asset is the richest household-level data set available for CTV targeting in India. Jio Ads' targeting capabilities are built on this data stack.
Jio set-top box and bundled TV
JioFiber packages sometimes include a Jio set-top box that runs the JioPages OS — Reliance's proprietary smart TV interface. The JioPages home screen presents JioCinema prominently alongside access to other installed apps (YouTube, Netflix, Prime Video). JioPages home screen advertising is an emerging format — showing ads at the OS layer before any app is opened.
The Jio set-top box audience is distinct from the broader smart TV audience in one important way: these are households that came to CTV through their broadband provider, not through a smart TV purchase decision. They may be less engaged with the CTV platform ecosystem but are identifiable as JioFiber subscribers for targeting purposes.
Advertising through the JioFiber audience
There is no separate "JioFiber advertising" product — advertisers reach JioFiber households primarily through JioCinema, which is where those households consume streaming content. The JioFiber data advantage is baked into Jio Ads' targeting capabilities: when buying JioCinema CTV inventory through Jio Ads, the geographic and household targeting is enriched by JioFiber subscriber data.
Practical implications for planners:
- Tier-2 city targeting: JioFiber's expansion into tier-2 cities means that a geographically targeted JioCinema buy (Jaipur, Lucknow, Indore, etc.) increasingly reaches JioFiber households — identified by address, not inferred from behaviour.
- Household income targeting: JioFiber plan tier (30 Mbps vs 300 Mbps vs 1 Gbps) is a proxy for household income. Higher-tier subscribers correlate with higher income. This data informs Jio Ads' income targeting segments.
- Connected TV device certainty: JioFiber households with a Jio set-top box or smart TV are definitively CTV households — there is no ambiguity about whether streaming happens on a mobile or a TV screen, as there would be with mobile data subscribers.
JioFiber and the future of India CTV
JioFiber's expansion trajectory suggests that the India CTV household base will continue growing into tier-2 and tier-3 cities over the next 3–5 years. Jio AirFiber accelerates this by removing the physical constraints on fibre deployment. As each new JioFiber market comes online, it adds a cohort of CTV-capable households who default toward JioCinema as their primary streaming platform.
For advertisers with national or semi-national reach targets, this means India CTV's addressable universe is expanding — and the new households entering the CTV universe are skewing toward the tier-2 demographic profile (aspirational middle class, family-oriented, high sports viewing) rather than the metro SEC A profile that characterised early CTV adoption.
