Samir Jain, the vice chairman and managing director (VCMD) of the Times Group, on Saturday said the role of media should be of a 'watchgod' and not just a watchdog. Speaking at the 7th edition of the Times Literature Festival in New Delhi, Samir Jain said it's a good thing if people believe that dog is a man's best friend. "But we do not have to be a barking dog, we should not always speak in a critical tone. People should feel happy and joyful after reading newspapers," Samir Jain said at the event in the presence of Union minister of railways, communications and electronics & IT Ashwini Vaishnaw, who was the chief guest at the event.
