The Viral Fever, abbreviated to TVF, is an Indian video on demand and over-the-top media service and YouTube channel started by TVF Media Labs in 2010, and currently owned and operated by Contagious Online Media Network Private Limited. According to the founder Arunabh Kumar, the thought behind starting TVF was to reach out to the younger generation who seldom watch television entertainment.

The Viral Fever was one of the early arrivals on the Indian digital entertainment segment with videos covering a range of topics on Indian politics, movies, lifestyle, and emerging social concepts. The Viral Fever was the pioneer of web series in India with cult hits like Permanent Roommates, Hostel Daze, TVF Pitchers and TVF Tripling.

The company runs the app and website TVFPlay to host their videos. TVF conceptualised the idea of promoting movies through the creation and distribution of original digital content. The Ishq Wala song series is one such venture.

Their first web series, Permanent Roommates, debuted in 2014. It was the second most-viewed long-form web series in the world by June 2015. A second original series titled TVF Pitchers was released in June 2015. It portrays engineers at different companies who quit their jobs to create a startup company. Owing to its growing popularity, with both TVF Pitchers and Permanent Roommates being watched by millions around the globe, the company received $10 million in funding from Tiger Global in February 2016.
