The Telecom Regulatory Authority of India (TRAI) has issued show cause notices to leading television broadcasters, including Zee Entertainment, Sun TV Network, and Network18, for allegedly exceeding the 12-minute advertising limit per clock hour. This action revives a decade-old dispute, with broadcasters having 15 days to respond. The matter is currently sub judice, with the Delhi High Court having granted interim relief to broadcasters in 2013.
