Friday is that one day of the week which is synonymous with movie premieres. And now even our television industry is not far behind. Take today's Friday the 18th for instance when not one, not two but three mega budget and much talked about shows hit the airwaves - Sahara One's Biggest Loser Jeetega (9.30 pm), Star Plus' Star Voice Of India (10pm) and Star One's The Great Indian Laughter Challenge 3 (9pm).
