Media, in the chennai floods played a major role in passing messages.
There were instances where many of the nationalized channels like The Times Now, Headlines Today, etc turned on helplines to help the victims. They also took to the social platform by communicating messages from one person to another.
Media helped showcase how people in Chennai, ahead of the situation they were facing, joined hands and helped everyone regardless of the differences. Media also portrayed how differences in time of natural calamities are negligible.

Hope it helps.
Cheers! :)
