According to the Pew Research Center, a majority of Americans at least occasionally receive news from social media.  Because of algorithms on social media which filter and display news content which are likely to match their users’ political preferences, a potential impact of receiving news from social media includes an increase in political polarization due to selective exposure.  Political polarization refers to when an individual's stance on a topic is more likely to be strictly defined by their identification with a specific political party or ideology than on other factors. Selective exposure occurs when an individual favors information which supports their beliefs and avoids information which conflicts with their beliefs. A study by Hayat and Samuel-Azran conducted during the 2016 U.S. presidential election observed an “echo chamber” effect of selective exposure among 27,811 Twitter users following the content of cable news shows.  The Twitter users observed in the study were found to have little interaction with users and content whose beliefs were different from their own, possibly heightening polarization effects. 
Social Media is the next big marketing giant, be it Twitter for Business, a product review at Periscope (though not everyone knows about it) or a successful ad campaign on the Facebook with a tremendous reach to the potential clients. Of all, Facebook is my best bet as it has directly favored my test tube business with a mere $500 ad campaign with $5000 increase in profits.
Many home party plans now offer consultants the opportunity to earn a living without ever holding an in-home show. Social media tools and virtual party technology like scheduling apps and graphics creation are widely available (as are the tutorials for figuring out how to use them). And almost every company today offers their reps a replicated website for selling and sharing online.
According to a 2016 article diving into the topic of sharing privately and the effect social media has on expectations of privacy, "1.18 billion people will log into their Facebook accounts, 500 million tweets will be sent, and there will be 95 million photos and videos posted on Instagram" in a day. Much of the privacy concerns individuals face stem from their own posts on a form of social network. Users have the choice to share voluntarily, and has been ingrained into society as routine and normative. Social media is a snapshot of our lives; a community we have created on the behaviors of sharing, posting, liking, and communicating. Sharing has become a phenomenon which social media and networks have uprooted and introduced to the world. The idea of privacy is redundant; once something is posted, its accessibility remains constant even if we select who is potentially able to view it. People desire privacy in some shape or form, yet also contribute to social media, which makes it difficult to maintain privacy. Mills offers options for reform which include copyright and the application of the law of confidence; more radically, a change to the concept of privacy itself.
Mobile social media refer to the use of social media on mobile devices such as smartphones and tablet computers. Mobile social media are a useful application of mobile marketing because the creation, exchange, and circulation of user-generated content can assist companies with marketing research, communication, and relationship development. Mobile social media differ from others because they incorporate the current location of the user (location-sensitivity) or the time delay between sending and receiving messages (time-sensitivity). According to Andreas Kaplan, mobile social media applications can be differentiated among four types:
Facebook jumped by 100 million monthly active users from 2.13 billion in December 2017 to 2.23 billion as of June 30, 2018. The rate of growth seems to continue at 15 million active users per month. So, by the end of the year we should see 2.35 billion Facebook monthly active users. Here’s the post where Zuckerberg announced the news about reaching the 2 billion milestone:
The best part is that Google is a $30B company and there is no ways to contact them other then a single phone number. Here is when I get little upset, people know about google, but everyone still uses it like there isnt any other choices. Well, actually there isnt. Social sites are just for gather info about you and use it to make money. For us its just a way to communicate with others.
Checking updates on friends' activities on social media is associated with the "fear of missing out" (FOMO), the "pervasive apprehension that others might be having rewarding experiences from which one is absent". FOMO is a social anxiety characterized by "a desire to stay continually connected with what others are doing". It has negative influences on people's psychological health and well-being because it could contribute to negative mood and depressed feelings.
Twitter is increasingly a target of heavy activity of marketers. Their actions, focused on gaining massive numbers of followers, include use of advanced scripts and manipulation techniques that distort the prime idea of social media by abusing human trustfulness. British-American entrepreneur and author Andrew Keen criticizes social media in his book The Cult of the Amateur, writing, "Out of this anarchy, it suddenly became clear that what was governing the infinite monkeys now inputting away on the Internet was the law of digital Darwinism, the survival of the loudest and most opinionated. Under these rules, the only way to intellectually prevail is by infinite filibustering." This is also relative to the issue "justice" in the social network. For example, the phenomenon "Human flesh search engine" in Asia raised the discussion of "private-law" brought by social network platform. Comparative media professor José van Dijck contends in her book "The Culture of Connectivity" (2013) that to understand the full weight of social media, their technological dimensions should be connected to the social and the cultural. She critically describes six social media platforms. One of her findings is the way Facebook had been successful in framing the term 'sharing' in such a way that third party use of user data is neglected in favour of intra-user connectedness.
Someone who knows a thing or two about building an audience, strategic partnerships, and making a living off of being authentic and niched online is Michell C. Clark, social entrepreneur and cultural curator. Clark’s entrepreneurial journey began eight years ago online. And now with an audience of over 75,000 people, including major brands, he helps business owners and entrepreneurs transform their social media presence to help them achieve their professional goals.
Some of the teens I spoke to were concerned about how technologies such as Snap Map – a Snapchat feature that tracks your friends geographically, in real time – were spreading through their schools, and mistrustful of the privacy consequences of being surveilled by your followers wherever you go. “Snap Map is this big thing with a lot of my friends, but there is a sense of privacy that is being breached as well,” Isabelle says.
Cyberbullying/Cyberstalking: Children and teenagers are especially susceptible to cyberbullying because they take more risks when it comes to posting on social media. And now that we all interact on social media via our mobile devices, most major platforms make it possible to share our locations, opening up the doors for cyberstalkers to target us.
Use a service like Flickr to get people acquainted with your work, offering photos they can use on their website for free under the Creative Commons license. Once you’ve built up a following, join another stock photography site like Shutterstock or iStockphoto where users will pay for the opportunity to use your pictures on their blogs. You can make up to $120 off of one paid download of your photo. Even if you get compensated at a lower level, the money can really add up if you take a lot of quality photographs.
Observers have noted a range of positive and negative impacts of social media use. Social media can help to improve an individual's sense of connectedness with real or online communities, and can be an effective communication (or marketing) tool for corporations, entrepreneurs, nonprofit organizations, advocacy groups, political parties, and governments. At the same time, concerns have been raised about possible links between heavy social media use and depression, and even the issues of cyberbullying, online harassment and "trolling". Currently, about half of young adults have been cyberbullied, and of those, 20% said that they have been cyberbullied regularly. Another survey in the U.S. applied the Precaution Process Adoption Model to cyberbullying on Facebook among 7th grade students. According to this study, 69% of 7th grade students claim to have experienced cyberbullying, and they also said that it was worse than face-to-face bullying. Both the bully and the victim are negatively affected, and the intensity, duration, and frequency of bullying are the three aspects that increase the negative effects on both of them.
