Value of Kalanithi Maran's Sun TV Network, a regional broadcasting powerhouse he founded in 1993, rose on higher ad revenues, even as he had to sell a small chunk of his stake to comply with public holding rules. Maran upped his holding in his loss-making budget airline SpiceJet to 50%, even as shares dipped. The airline, which is rumored to be mulling a stake sale, faces imminent competition from soon to-be-launched AirAsia India. Recently, analysts questioned SunTV's purchase of a new corporate jet. Sun also owns Indian Premier League cricket team Sunrisers Hyderabad which it bought last year for $80 million.
