Tata Sky has launched a new mobile app that allows subscribers to access 54 live TV channels on their mobile devices for a monthly payment of Rs. 60. The app aims to make content discovery and access easier for users who are busy and on the move. It addresses the "three W's principle" of allowing users to watch whichever channels they want, whenever they want, and wherever they are. Other DTH operators and broadcasters have also launched similar mobile apps to expand their reach among mobile users.
