South India — comprising Tamil Nadu, Andhra Pradesh, Telangana, Karnataka, and Kerala — is the most economically developed and CTV-penetrated regional market outside India's top metros. Higher per-capita incomes, strong local cinema cultures, platform investment in regional language content, and a tech-industry hub in Bengaluru combine to make South India a premium CTV market that is systematically underserved by advertisers who plan only at the national Hindi level.
Why South India CTV punches above its weight
Economic profile
The southern states contain three of India's five largest state economies by GDP — Maharashtra and Uttar Pradesh are the others. Karnataka (driven by Bengaluru's IT industry), Tamil Nadu (manufacturing and services), and Telangana (Hyderabad tech hub) all have per-capita incomes significantly above the national average. Higher incomes translate directly to higher smart TV penetration, more reliable home broadband, and spending power for premium CTV platforms.
Cinema culture and CTV viewing behaviour
Tamil and Telugu cinema are among the most vibrant film industries in the world by output and box office. Films from these industries have massive first-day-first-show audiences and extremely rapid OTT viewing after theatrical release. When a major Tamil or Telugu film hits JioCinema, Prime Video, or Sun NXT, South Indian urban households stream it on the first available day in large numbers — on CTV screens in their living rooms. This creates predictable, high-intensity CTV viewing events that do not exist for the Hindi film market at the same density.
Regional platform strength
South Indian CTV audiences have dedicated platforms that serve their content preferences — Sun NXT (Tamil, Telugu, Kannada, Malayalam), Aha (Telugu-exclusive), and Hotstar's regional network (Star Vijay for Tamil, Star Maa for Telugu, Asianet for Malayalam). These platforms have significant CTV audience bases that are not captured by national Hindi-first platform data.
State-by-state South India CTV breakdown
Tamil Nadu and Chennai
Tamil Nadu has one of India's highest smart TV penetration rates among southern states. Chennai is a major metro with high CTV penetration. Secondary cities — Coimbatore, Madurai, Trichy, Salem — are significant CTV markets. Tamil language content drives CTV viewing: Sun NXT for Sun TV network content, Hotstar for Star Vijay and some cricket, YouTube for Tamil music and film content.
Tamil Nadu cricket: while IPL is national, Tamil Nadu has the TNPL (Tamil Nadu Premier League) — a domestic T20 league with strong local viewership that streams on platforms including JioCinema. IPL's Chennai Super Kings have one of the most loyal fan bases in India — CSK fan households are among the most engaged IPL CTV viewers.
Andhra Pradesh and Telangana
Hyderabad (Telangana) is a major tech and BFSI hub with metro-level CTV penetration. The Telugu entertainment industry (Tollywood) is one of the highest-grossing film industries in India and drives intense OTT streaming demand on Prime Video, Aha, and JioCinema. Aha, a Telugu-exclusive OTT platform, has carved a significant CTV audience in both states. The IPL's Sunrisers Hyderabad has strong local followership. Andhra Pradesh's tier-1 cities (Visakhapatnam, Vijayawada) are secondary but growing CTV markets.
Karnataka and Bengaluru
Bengaluru is India's CTV capital by per-capita penetration — a tech-industry workforce with high incomes, early adopter behaviour, multi-OTT subscriptions, and premium smart TV hardware. Kannada language content is served primarily by Sun NXT (Udaya TV network) and Hotstar (Star Suvarna). But Bengaluru's CTV audience is predominantly bilingual — consuming both Kannada and English/Hindi content — making it accessible to national-level campaigns in ways that more linguistically homogeneous South Indian markets are not.
Kerala
Kerala has India's highest literacy rate and a highly educated, culturally engaged population. Malayalam cinema (Mollywood) produces critically acclaimed, internationally recognised films that attract strong OTT streaming demand. Sun NXT (Asianet network) and Hotstar (Asianet content) are primary platforms for Malayalam CTV content. Kerala's NRI (Non-Resident Indian) diaspora — concentrated in the Gulf states — has significant Kerala-targeted OTT viewership that inflates platform audience claims for Malayalam content globally.
Advertising in South India CTV
Primary buying routes
- YouTube (DV360): The most accessible programmatic route for South Indian language targeting. Tamil, Telugu, Kannada, and Malayalam music labels (T-Series, Lahari, Sony Music South, Kerala-specific channels) have massive YouTube audiences. DV360 language targeting reaches South Indian CTV viewers at scale.
- Sun NXT (direct): For significant Tamil, Telugu, Kannada, or Malayalam CTV reach, Sun NXT is the dominant platform. Requires direct deal or agency relationship with Sun TV Group's ad sales. Not open programmatic.
- Aha (direct): For Telugu-focused campaigns, Aha's direct sales team. Smaller scale than Sun NXT but highly targeted to the Telugu-speaking CTV audience.
- Hotstar regional networks: Star Vijay (Tamil), Star Maa (Telugu), Asianet (Malayalam), Star Suvarna (Kannada) all stream on Hotstar. Reaching South Indian language audiences through Hotstar uses the same buying routes as national Hotstar buys but with content and geography targeting to focus delivery.
CPM expectations
South Indian CTV CPMs are generally lower than national Hindi CTV inventory, reflecting lower advertiser demand. Directional ranges on Sun NXT and YouTube regional language inventory: Rs 60–130 CPM. Lower competition means South Indian CTV can be a more efficient buy than national inventory for brands with genuine South Indian audience targets.
Creative: localisation matters
Tamil, Telugu, Kannada, and Malayalam audiences respond significantly better to creative in their language than to dubbed Hindi ads. The cultural distinctiveness of South Indian markets — particularly Tamil Nadu and Kerala — means brand localisation is not just a nicety but a material performance driver. Even a voice-over dub with local cultural references outperforms a national creative running unchanged.
