Uber drapes their cars in the French flag on the app in the wake of the Paris attacks.

Social media has given brands a larger soapbox than ever before. During times of tragedy, it can give them a platform to help victims immediately.

During the Paris attacks, many companies offered services for free to help out or tweeted support for the victims. Uber suspended surge pricing and sent out message alerts advising Parisians to stay indoors in accordance with what authorities were stating. AirBnB offered free accommodations for stranded travelers on the company's Disaster Response page.
