At school, social media can be a brutal barometer of popularity. “If you meet someone new and they ask for your Instagram and you only have 80 followers,” says Sharp, “they’re going to think: ‘You’re not that popular’, but if you have 2,000 followers they’re going to be like: ‘You’re the most popular person in school.’” Sharp quit social media at 13. “I’d rather not know what other people think of me.”
Another trend that influences the way youth communicates is the though the use of hashtags. With the introduction of social media platforms such as Twitter, Facebook and Instagram, the hashtag was created to easily organize and search for information. Hashtags can be used when people want to advocate for a movement, store content or tweets from a movement for future use, and allow other social media users to contribute to a discussion about a certain movement by using existing hashtags. Using hashtags as a way to advocate for something online makes it easier and more accessible for more people to acknowledge it around the world.As hashtags such as #tbt ("throwback Thursday") become a part of online communication, it influenced the way in which youth share and communicate in their daily lives. Because of these changes in linguistics and communication etiquette, researchers of media semiotics[who?] have found that this has altered youth's communications habits and more.[vague]
"Social media" is a way for people to communicate and interact online. While it has been around since the dawn of the World Wide Web, in the last 10 years or so we've seen a surge in both the number and popularity of social media sites. It's called social media because users engage with (and around) it in a social context, which can include conversations, commentary, and other user-generated annotations and engagement interactions.
Though research has shown evidence that social media plays a role in increasing political polarization, it has also shown evidence that social media use leads to a persuasion of political beliefs.  An online survey consisting of 1,024 U.S. participants was conducted by Diehl, Weeks, and Gil de Zuñiga, which found that individuals who use social media were more likely to have their political beliefs persuaded than those who did not.  In particular, those using social media as a means to receive their news were the most likely to have their political beliefs changed.  Diehl et al. found that the persuasion reported by participants was influenced by the exposure to diverse viewpoints they experienced, both in the content they saw as well as the political discussions they participated in.  Similarly, a study by Hardy and colleagues conducted with 189 students from a Midwestern state university examined the persuasive effect of watching a political comedy video on Facebook.  Hardy et. al found that after watching a Facebook video of the comedian/political commentator John Oliver performing a segment on his show, participants were likely to be persuaded to change their viewpoint on the topic they watched (either payday lending or the Ferguson protests) to one that was closer to the opinion expressed by Oliver.  Furthermore, the persuasion experienced by the participants was found to be reduced if they viewed comments by Facebook users which contradicted the arguments made by Oliver. 
The commercial development of social media has been criticized as the actions of consumers in these settings has become increasingly value-creating, for example when consumers contribute to the marketing and branding of specific products by posting positive reviews. As such, value-creating activities also increase the value of a specific product, which could, according to the marketing professors Bernad Cova and Daniele Dalli, lead to what they refer to as "double exploitation". Companies are getting consumers to create content for the companies' websites for which the consumers are not paid.
