Television has been a medium of wide reach for many years now. From daily soaps, comedy to crime shows, the family viewing experience has made it a popular medium. Now, in a move to make the characters and stories more relatable, showmakers are not sticking to a vague regional identity. They are including more and more regional dialects in the dialogues for a stronger connect and well defined sketch of the characters.
For instance, in popular daily soap 'Anupamaa', the family is shown to be of Gujarati descent, hence even the dialogues and diction is also of a person from Gujarat. Similarly, in the show 'Udaariyan', many dialogues are in Punjabi, something that Hindi shows earlier didn't pay much attention to.
