Excessive use of digital technology, like social media, by adolescents can cause disruptions in their physical and mental health, in sleeping patterns, their weight and levels of exercise and notably in their academic performance. Research has continued to demonstrate that long hours spent on mobile devices have shown a positive relationship with an increase in teenagers' BMI and a lack of physical activity. Moreover, excessive internet usage has been linked to lower grades compared to users who don't spend an excessive amount of time online, even with a control over age, gender, race, parent education and personal contentment factors that may affect the study.[147] In a recent study, it was found that time spent on Facebook has a strong negative relationship with overall GPA.[148] The use of multiple social media platforms is more strongly associated with depression and anxiety among young adults than time spent online. The analysis showed that people who reported using the most platforms (7 to 11) had more than three times the risk of depression and anxiety than people who used the fewest (0 to 2).[149] Social media addiction and its sub-dimensions have a high positive correlation. The more the participants are addicted to social media, the less satisfied they are with life.[150]
It is widely believed that young people are hopelessly devoted to social media. Teenagers, according to this stereotype, tweet, gram, Snap and scroll. But for every young person hunched over a screen, there are others for whom social media no longer holds such an allure. These teens are turning their backs on the technology – and there are more of them than you might think.
Like podcasting, webinars can be a cost-effective revenue model for influencers and content creators. A webinar is essentially a seminar conducted over the internet and is usually for an educational purpose to provide information in an engaging, tutorial-style format. Webinars can either be live, or they can be pre-recorded and shared across video, blog and social media platforms.
The idea that social media are defined simply by their ability to bring people together has been seen as too broad, as this would suggest that fundamentally different technologies like the telegraph and telephone are also social media.[18] The terminology is unclear, with some early researchers referring to social media as social networks or social networking services in the mid 2000s.[4] A more recent paper from 2015[2] reviewed the prominent literature in the area and identified four common features unique to then-current social media services:

Some social media sites have potential for content posted there to spread virally over social networks. The term is an analogy to the concept of viral infections, which can spread rapidly from person to person. In a social media context, content or websites that are "viral" (or which "go viral") are those with a greater likelihood that users will reshare content posted (by another user) to their social network, leading to further sharing. In some cases, posts containing popular content or fast-breaking news have been rapidly shared and reshared by a huge number of users. Many social media sites provide a specific functionality to help users reshare content, such as Twitter's retweet button, Pinterest's pin function, Facebook's share option or Tumblr's reblog function. Businesses have a particular interest in viral marketing tactics because a viral campaign can achieve widespread advertising coverage (particularly if the viral reposting itself makes the news) for a fraction of the cost of a traditional marketing campaign, which typically uses printed materials, like newspapers, magazines, mailings, and billboards, and television and radio commercials. Nonprofit organizations and activists may have similar interests in posting content on social media sites with the aim of it going viral. A popular component and feature of Twitter is retweeting. Twitter allows other people to keep up with important events, stay connected with their peers, and can contribute in various ways throughout social media.[25] When certain posts become popular, they start to get retweeted over and over again, becoming viral. Hashtags can be used in tweets, and can also be used to take count of how many people have used that hashtag.

Use analytics - It’s important to pause every now and then and take stock of what has done well on your social media accounts and what hasn’t. Sites like Fanpage Karma and Squarelovin (Instagram only), will provide data on which of your posts have been most popular. You can use this to identify what content tends to work best, and the best time to post it.
Once you have a sufficient number of fans and followers on different channels, you should start promoting and selling your online coaching service. Your coaching service can be offline too but that entirely depends upon your business goals. But it is much easier to do online coaching as it does not involve overheads like a classroom and other conference equipment. You just need an internet connection on your laptop, to begin with!
As social networking becomes more popular among older and younger generations, sites such as Facebook and YouTube, gradually undermine the traditionally authoritative voices of news media. For example, American citizens contest media coverage of various social and political events as they see fit, inserting their voices into the narratives about America's past and present and shaping their own collective memories.[93][94] An example of this is the public explosion of the Trayvon Martin shooting in Sanford, Florida. News media coverage of the incident was minimal until social media users made the story recognizable through their constant discussion of the case. Approximately one month after the fatal shooting of Trayvon Martin, its online coverage by everyday Americans garnered national attention from mainstream media journalists, in turn exemplifying media activism. In some ways, the spread of this tragic event through alternative news sources parallels that of Emmitt Till – whose murder by lynching in 1955 became a national story after it circulated African American and Communist newspapers.
For individuals, social media is used to keep in touch with friends and extended family, network for career opportunities, find people from all over the globe who share a common interest, share content and more. Those who engage in these activities are part of a virtual social network. For businesses, social media is an indispensable tool for finding and engaging with customers, sales, advertising and promotion, gauging trends and offering customer service. Governments and politicians utilize social media to engage with constituents and voters.
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]
There has been rapid growth in the number of US patent applications that cover new technologies related to social media, and the number of them that are published has been growing rapidly over the past five years. There are now over 2000 published patent applications.[39] As many as 7000 applications may be currently on file including those that haven't been published yet. Only slightly over 100 of these applications have issued as patents, however, largely due to the multi-year backlog in examination of business method patents, patents which outline and claim new methods of doing business.[40]

A sponsored social media post is when a brand engages an influencer to create content featuring the brand (it could be one post, two posts, or a series of posts) and share it with their followers. There are many forms of sponsored social media posts, from sharing the brand owned content, developing unique imagery, promoting a new product, launching a new brand or generating exposure among a new target market.  

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.[11] 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.
