Pravin Kulkarni grimaces on being told that advertising on television will become costlier very soon. “It’s so expensive as it is. How much more should we pay now?” complains Kulkarni, Parle Products’ general manager (marketing), not really expecting an answer. Still, the buzz at media buying agencies is that in the coming months, ad rates will be hiked at least 15% across television channels. It’s not an arbitrary move. Come October, no channel can have more than 12 minutes of advertising every hour (and that includes two minutes of promos). The exception, of course, is cricket, where a commercial break marks the end of every over.
