Why These Terms Matter in India’s Market
India’s digital advertising market reached over $6 billion in 2025 and is growing rapidly. Programmatic now accounts for the majority of digital display advertising spend in India — driven by:
- Over 700 million smartphone users creating massive mobile inventory
- IPL streaming on Hotstar and JioCinema driving CTV advertising growth
- OTT platforms including Netflix, Amazon Prime and Zee5 opening programmatic inventory
- Google, Meta, The Trade Desk and Samsung Ads all investing heavily in India
Understanding these terms is not just academic — it directly affects how you buy, sell and optimise digital media in one of the world’s fastest-growing advertising markets.
