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. 
There are several negative effects to social media which receive criticism, for example regarding privacy issues, information overload 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" 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.
Now as a coach, he works with clients to come up with plans to help them reach their goals. “I think a great thing that I am able to do with my coaching is talk to my clients about not the specific plan that is going to work for them but a plan they believe in enough to execute to the best of their abilities. So, we’re not focused on the social media trends. We’re digging deeper and we’re talking about things that will drive them individually,” says Clark.
There are prominent YouTube content creators who have made substantial amounts of money with this program, but they are the exception rather than the rule. It would take a lot of time, strategy and sheer luck to make money on YouTube. However, this is a good thing to keep in mind with advertising in general. Unless you're already getting a lot of views and clicks, you're not going to make a lot of money on them.
A 2014 Pew Research Center survey found that 91% of Americans "agree" or "strongly agree" that people have lost control over how personal information is collected and used by all kinds of entities. Some 80% of social media users said they were concerned about advertisers and businesses accessing the data they share on social media platforms, and 64% said the government should do more to regulate advertisers.
Thanks Mike for your comment. I don’t trust Facebook either. There’s been many times where I have seen ads come up on FB of subjects that I’ve been talking about offline. Its happened on more than one occasion which is a bit scary if you ask me. Although I do think FB has had its best days and will gradually fall in user numbers as new and innovative platforms come to market over the next 5 years.
Be sure to integrate social media into your marketing efforts as early as possible to help amplify and solidify your work rather than waiting until the end of a planning cycle to explore social options. If a social presence is clear from the start, your branding will benefit from additional customer touchpoints, PR will see a lift in impressions and reach, and customer service can proactively listen and activate where necessary.
Social media often features in political struggles to control public perception and online activity. In some countries, Internet police or secret police monitor or control citizens' use of social media. For example, in 2013 some social media was banned in Turkey after the Taksim Gezi Park protests. Both Twitter and YouTube were temporarily suspended in the country by a court's decision. A new law, passed by Turkish Parliament, has granted immunity to Telecommunications Directorate (TİB) personnel. The TİB was also given the authority to block access to specific websites without the need for a court order. Yet TİB's 2014 blocking of Twitter was ruled by the constitutional court to violate free speech. More recently, in the 2014 Thai coup d'état, the public was explicitly instructed not to 'share' or 'like' dissenting views on social media or face prison. In July of that same year, in response to WikiLeaks' release of a secret suppression order made by the Victorian Supreme Court, media lawyers were quoted in the Australian media to the effect that "anyone who tweets a link to the Wikileaks report, posts it on Facebook, or shares it in any way online could also face charges".
Usenet, which arrived in 1979, was beat by a precursor of the electronic bulletin board system (BBS) known as Community Memory in 1973. True electronic bulletin board systems arrived with the Computer Bulletin Board System in Chicago, which first came online on 16 February 1978. Before long, most major cities had more than one BBS running on TRS-80, Apple II, Atari, IBM PC, Commodore 64, Sinclair, and similar personal computers. The IBM PC was introduced in 1981, and subsequent models of both Mac computers and PCs were used throughout the 1980s. Multiple modems, followed by specialized telecommunication hardware, allowed many users to be online simultaneously. Compuserve, Prodigy and AOL were three of the largest BBS companies and were the first to migrate to the Internet in the 1990s. Between the mid-1980s and the mid-1990s, BBSes numbered in the tens of thousands in North America alone. Message forums (a specific structure of social media) arose with the BBS phenomenon throughout the 1980s and early 1990s. When the Internet proliferated in the mid-1990s, message forums migrated online, becoming Internet forums, primarily due to cheaper per-person access as well as the ability to handle far more people simultaneously than telco modem banks.
