In recent years, social media has 
played a key role in bringing about dramatic changes in business, consumer cultures, and even whole societies. Businesses are becoming more transparent and are also held accountable for their actions as citizens are empowered with more real-time and unbiased information. Consumers are (perhaps reluctantly) accepting a reduced amount of privacy as a price they are willing to pay as they feel the urge to share their day-to-day lives with a wider set of “friends”. Societies undergo revolutionary transformations as social media serves as the communication platform needed for collective action to be mobilized against oppressive regimes such as in the case of the 2011 revolutions in Tunisia and Egypt.
