Social media has allowed for mass cultural exchange and intercultural communication. As different cultures have different value systems,[vague] cultural themes, grammar, and world views, they also communicate differently. The emergence of social media platforms fused together different cultures and their communication methods, blending together various cultural thinking patterns and expression styles.
Once you’ve built up a following and proven yourself to be knowledgeable about a certain subject, write and publish an e-book that your consistent social media presence will have persuaded your fans to buy. You can release it simply as a PDF or through services like Amazon’s Kindle program. Carol Tice demonstrated her expertise in the topics of freelance writing on social media, which she translated into major e-book sales. Some people make up to $100,000 a month off of the Kindle program alone, but that’s an example of extreme success. The average e-book brings in about $423 per year. But if your book is better written, better designed and better marketed than 90% of your competitors’, you will probably make more than that.
Many teenagers suffer from sleep deprivation as they spend long hours at night on their phones, and this, in turn, could affect grades as they will be tired and unfocused in school. Social media has generated a phenomenon known as " Facebook depression", which is a type of depression that affects adolescents who spend too much of their free time engaging with social media sites.

Copyblogger published an interesting article several years ago, making the argument that blogs are indeed social media, despite the fact that people tend to put them in a category all on their own these days. In fact, blogs are one of the oldest forms of social media that dominated the web long before we were friending and following everyone on social networks.
This is the biggest social media network on the Internet, both in terms of total number of users and name recognition. Founded on February 4, 2004, Facebook has within 12 years managed to accumulate more than 1.59 billion monthly active users and this automatically makes it one of the best mediums for connecting people from all over the world with your business. It is estimated that more than 1 million small and medium-sized businesses use the platform to advertise their business.
Social media marketing has increased due to the growing active user rates on social media sites. For example, Facebook currently has 2.2 billion users, Twitter has 330 million active users and Instagram has 800 million users. One of the main uses is to interact with audiences to create awareness of their brand or service, with the main idea of creating a two-way communication system where the audience and/or customers can interact back; providing feedback as just one example. Social media can be used to advertise; placing an advert on Facebook's Newsfeed, for example, can allow a vast number of people to see it or targeting specific audiences from their usage to encourage awareness of the product or brand. Users of social media are then able to like, share and comment on the advert, becoming message senders as they can keep passing the advert's message on to their friends and onwards.
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. 
Networks formed through social media change the way groups of people interact and communicate. They "introduce substantial and pervasive changes to communication between organizations, communities, and individuals." These changes are the focus of the emerging fields of technoself studies. Social media differ from paper-based media (e.g., magazines and newspapers) and traditional electronic media such as TV broadcasting in many ways, including quality, reach, frequency, interactivity, usability, immediacy, and performance. Social media outlets operate in a dialogic transmission system (many sources to many receivers). This is in contrast to traditional media which operates under a monologic transmission model (one source to many receivers), such as a newspaper which is delivered to many subscribers, or a radio station which broadcasts the same programs to an entire city. Some of the most popular social media websites are Facebook (and its associated Facebook Messenger), Instagram, WhatsApp, Google+, Myspace, LinkedIn, Pinterest, Snapchat, Tumblr, Twitter, Viber, VK, WeChat, Weibo, Baidu Tieba, and Wikia. These social media websites have more than 100,000,000 registered users.
