Social media is the most powerful tool in today’s digital world. Without social media, it is not possible for businesses to promote their brand and reach out globally. There are numbers of social media platforms on which you can promote your brand, but not all have the same value. Thank you for the awesome list of most popular social media websites. We have to focus only on such social media that are relevant to our niche.
Even in the United States, the birth-country of Twitter, currently in 2015 the social network has 306 million accounts. Because there are likely to be many multi-account users, and the United States in 2012 had a population of 314.7 million, the adoption of Twitter is somewhat limited. Professor Matthew Auer of Bates College casts doubt on the conventional wisdom that social media are open and participatory. He also speculates on the emergence of "anti-social media" used as "instruments of pure control."
On social media, consumers are exposed to purchasing practices though peer sent, written messages. Learning through social media includes strategies such as "modeling, reinforcement, and social interaction mechanisms" all at the same time. A study, that focused on peer communication through social media, has revealed that communication between peers through social media is positively related to purchase intentions in a couple ways. First, is a direct impact through conformity. Second, is an indirect impact by stressing product engagement. Lastly, from this study, we learned that consumer-related communication between peers on social media has a positive relationship with product engagement. 
I’ve got a few e-mails relating to sponsored posts but never know if they’re legit. I think one time I replied and they wanted me to post something about how to save money when gambling at casinos. I’m pretty sure that would turn off a lot of readers (not that I have a lot of readers to begin with). Will have to look into it more though if there are ones which are about products/companies that I might actually like
Social media is used to fulfill perceived social needs, but not all needs can be fulfilled by social media. For example, lonely individuals are more likely to use the Internet for emotional support than those who are not lonely. Sherry Turkle explores these issues in her book Alone Together as she discusses how people confuse social media usage with authentic communication. She posits that people tend to act differently online and are less afraid to hurt each other's feelings. Additionally, studies on who interacts on the internent have shown that extraversion and openness have a positive relationship with social media, while emotional stability has a negative sloping relationship with social media. 
In a study examining the potential polarizing effects of social media on the political views of its users, Mihailidis and Viotty suggest that a new way of engaging with social media must occur to avoid polarization. The authors note that media literacies (described as methods which give people skills to critique and create media) are important to using social media in a responsible and productive way, and state that these literacies must be changed further in order to have the most effectiveness. In order to decrease polarization and encourage cooperation among social media users, Mihailidis and Viotty suggest that media literacies must focus on teaching individuals how to connect with other people in a caring way, embrace differences, and understand the ways in which social media has a realistic impact on the political, social, and cultural issues of the society they are a part of.
Becoming an affiliate is a great way to make money on social media without having a large follower count. As an affiliate, you are responsible for promoting a brand or its products on your social channels. This is usually done in the form of an affiliate link. When one of your followers clicks on it and makes a purchase, you earn a commission from it.
Are you a popular vlogger? Do you post a lot of funny animal videos that go viral? You might be able to make some income by joining the YouTube Partner Program, in which you allow Google to place ads at the beginning of your videos. You then share in that ad revenue. Grace Helbig is a prominent example of someone who’s made a living off of creating fun YouTube videos and promoting herself on other social media outlets. Admittedly, your chances of becoming a YouTube star and getting rich off it are low, but if you’ve got an engaging personality, sense of humor or a unique perspective than the YouTube Partner Program may be an avenue worth exploring.
The digital divide is a measure of disparity in the level of access to technology between households, socioeconomic levels or other demographic categories. People who are homeless, living in poverty, elderly people and those living in rural or remote communities may have little or no access to computers and the Internet; in contrast, middle class and upper-class people in urban areas have very high rates of computer and Internet access. Other models argue that within a modern information society, some individuals produce Internet content while others only consume it, which could be a result of disparities in the education system where only some teachers integrate technology into the classroom and teach critical thinking. While social media has differences among age groups, a 2010 study in the United States found no racial divide. Some zero-rating programs offer subsidized data access to certain websites on low-cost plans. Critics say that this is an anti-competitive program that undermines net neutrality and creates a "walled garden" for platforms like Facebook Zero. A 2015 study found that 65% of Nigerians, 61% of Indonesians, and 58% of Indians agree with the statement that "Facebook is the Internet" compared with only 5% in the US.
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.
Social media may have been influenced by the 1840s introduction of the telegraph in the US, which connected the country. 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.
