Modern bahus on TV is the latest trend

The credit should go to scriptwriters and producers who have the guts to support such scripts where the daughter-in-law is not the inferior member of the family.
Anandi of 'Balika Vadhu' has come up as a strong example as one of the bold bahus on Indian television. The female lead in the show has just not handled her family well but has gone forward to even take up the charge of being the 'Sarpanch' of her village. She is now shown teaching the women of her village their rights.
For instance, in an episode, she teaches a woman how to get a bank account made and put her savings there. Toral Rasputra, who plays Anandi in Balika Vadhu says, "That was an important episode on the show, since this actually happens in the rural India where the man of the family disrespects women's savings. They tend to spend that money on drinking and gambling. Lack of education works as a drawback for the deprived class and we made sure that people learn to teach others and help them out as the protagonist in the show did."
So, now television is not just about crying bahus and dominating mother in laws, it has grown and evolved with time and has the guts to showcase the developments happening in the society.
