Who uses "social media"?

 Social media is created for everyone, not just for the "young" people. Even though its true that the online social media today is mainly used by the age group from 12-34, it is also true that the sites that are mainly used by the young people, also support and are used by the adults.

 Therefor i conclude that all online social media are created to support a wide audience, but are forced to create alot of content for the larger group of people using it (aka. the "young" people). This makes alot of sence since a bigger the audience means a bigger the income.
