As social media usage has become increasingly widespread, social media has to a large extent come to be subjected to commercialization by marketing companies and advertising agencies.[187] Christofer Laurell, a digital marketing researcher, suggested that the social media landscape currently consists of three types of places because of this development: consumer-dominated places, professionally dominated places and places undergoing commercialization.[188] As social media becomes commercialized, this process have been shown to create novel forms of value networks stretching between consumer and producer[189] in which a combination of personal, private and commercial contents are created.[190]
After being “bugged” by his friends to get Instagram (he had stopped using Facebook aged 16), Johnson joined. He lasted six months. “If you’re having a bad day and scrolling through it, you’re constantly bombarded with pictures of people going to parties. Even if that’s not an accurate portrayal of their lives, that’s what you see. So I stopped using it. It became depressing. It was this competition of who’s the happiest.” He pauses. “Participating in that is not something I’m interested in.”

Studies have shown that self comparison on social media can have dire effects on physical and mental health because they give us the ability to seek approval and compare ourselves.[141] Social media has both a practical usage- to connect us with others, but also can lead to fulfillment of gratification.[142] In fact, one study suggests that because a critical aspect of social networking sites involve spending hours, if not months customizing a personal profile, and encourage a sort of social currency based on likes, followers and comments- they provide a forum for persistent "appearance conversations".[143] These appearance centered conversations that forums like Facebook, Instagram among others provide can lead to feelings of disappointment in looks and personality when not enough likes or comments are achieved. In addition, social media use can lead to detrimental physical health effects. A large body of literature associates body image and disordered eating with social networking platforms. Specifically, literature suggests that social media can breed a negative feedback loop of viewing and uploading photos, self comparison, feelings of disappointment when perceived social success is not achieved, and disordered body perception.[144] In fact, one study shows that the microblogging platform, Pinterest is directly associated with disordered dieting behavior, indicating that for those who frequently look at exercise or dieting "pins" there is a greater chance that they will engage in extreme weight-loss and dieting behavior.[145]
Overuse of social media has been likened to addiction and contributes to inattentiveness, stress and jealousy. Heavy social media use has been linked to depression. Social media as a conduit for misleading information and falsehoods has been well documented, such as in the 2016 U.S. presidential election. Such a phenomenon leverages the power of social media, allowing anyone to reach an audience of millions with content that lacks oversight or fact checking.
Social media might can also function as a supportive system for adolescents' health, because by using social media, adolescents are able to mobilize around health issues that they themselves deem relevant.[112] For example, in a clinical study among adolescent patients undergoing treatment for obesity, the participants' expressed that through social media, they could find personalized weight-loss content as well as social support among other adolescents with obesity[113] The same authors also found that as with other types of online information, the adolescents need to possess necessary skills to evaluate and identify reliable health information, competencies commonly known as health literacy.
There are several negative effects to social media which receive criticism, for example regarding privacy issues,[137] information overload[138] and Internet fraud. Social media can also have negative social effects on users. Angry or emotional conversations can lead to real-world interactions outside of the Internet, which can get users into dangerous situations. Some users have experienced threats of violence online and have feared these threats manifesting themselves offline. Studies also show that social media have negative effects on peoples' self-esteem and self-worth. The authors of "Who Compares and Despairs? The Effect of Social Comparison Orientation on Social Media Use and its Outcomes"[139] found that people with a higher social comparison orientation appear to use social media more heavily than people with low social comparison orientation. This finding was consistent with other studies that found people with high social comparison orientation make more social comparisons once on social media. People compare their own lives to the lives of their friends through their friends' posts. People are motivated to portray themselves in a way that is appropriate to the situation and serves their best interest. Often the things posted online are the positive aspects of people's lives, making other people question why their own lives are not as exciting or fulfilling. This can lead to depression and other self-esteem issues as well as decrease their satisfaction of life as they feel if their life is not exciting enough to put online it is not as good as their friends or family.[140]
If anything, social media is probably about to move more toward ephemeral sharing for quicker, more intimate sharing without the stress of having to blast something out to hundreds or thousands of followers that stays up there unless it's manually deleted. The pressure of garnering tons of likes and comments on regular social media posts also plays a huge factor, suggesting that more casual forms of social sharing, such as through stories, could be the way of the future.
Pinterest is a perfect platform for selling products. As a virtual pin-board, the social media service is commonly used by potential customers to “pin” items of interest that they might buy later. If you created a product or are in charge of marketing one, throw some photos of it on Pinterest to shine a spotlight on it. Look at great examples of companies that utilize Pinterest to its fullest potential like TODAY, Whole Foods Market and the Travel Channel here. If you can land a freelance job doing something similar you can hit it pretty big, but you probably need the right experience to be in the running. However, small businesses also want to promote on Pinterest, and they’re more likely to hire based on enthusiasm and a go-getter attitude, so maybe start making some cold calls and emails.
Social media may have been influenced by the 1840s introduction of the telegraph in the US, which connected the country.[10] ARPANET, which first came online in 1967, had by the late 1970s developed a rich cultural exchange of non-government/business ideas and communication, as clearly evidenced by ARPANET#Rules and etiquette's "A 1982 handbook on computing at MIT's AI Lab stated regarding network etiquette," and fully met the current definition of the term "social media" found in this article. The PLATO system launched in 1960, which was developed at the University of Illinois and subsequently commercially marketed by Control Data Corporation, offered early forms of social media with 1973-era innovations such as Notes, PLATO's message-forum application; TERM-talk, its instant-messaging feature; Talkomatic, perhaps the first online chat room; News Report, a crowd-sourced online newspaper and blog; and Access Lists, enabling the owner of a notesfile or other application to limit access to a certain set of users, for example, only friends, classmates, or co-workers. Tom Truscott and Jim Ellis conceived the idea of Usenet in 1979 at the University of North Carolina at Chapel Hill and Duke University, and it was established in 1980.
