This shift in political patronage only make matters worse for Kalanithi Maran, executive chairman, Sun TV Network. In fact, Sun TV’s fortunes have reversed entirely from the time when Maran’s granduncle, M Karunanidhi, was the state’s CM. Its success was most obvious between 2007 and 2011 when revenues zoomed from Rs.726 crore to Rs.1,970 crore, a growth of over 171%. Much of this growth was on account of its dominant position in the cable distribution business, which went out to 1.75 crore homes across the state. “A non-Sun network channel could never get on the prime band. With this kind of monopoly, their distribution revenue was huge,” says P Sakilan, president, Thamizhaga Cable Operators Welfare Association. During the five years the DMK was in power, Sun’s subscription revenue soared 150% from Rs.201 crore to Rs.502 crore. For FY15, Sun’s total revenue was at Rs.2,243 crore, a growth of just 14% compared with that of FY11. More importantly, its ad revenue growth has been oscillating between single digits for the past two years. “It is an open secret that Sun today is reducing its advertising rates,” says a media planner. The company could not be reached for comments.
