On the other hand, the integration of social media in the business world can also pose challenges. Social media policies are designed to set expectations for appropriate behavior and ensure that an employee's posts will not expose the company to legal problems or public embarrassment. Such policies include directives for when an employee should identify himself as a representative of the company on a social networking website, as well as rules for what types of information can be shared.
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:
Younger generations are becoming more involved in politics due to the increase of political news posted on social media. Due to the heavier use of social media among younger generations, they are exposed to politics more frequently, and in a way that is integrated into their online social lives. Social media was influential in the widespread attention given to the revolutionary outbreaks in the Middle East and North Africa during 2011. During the Tunisian revolution in 2011, people used Facebook to organize meetings and protests. However, there is debate about the extent to which social media facilitated this kind of change.
This is part of a wider trend. According to a study by US marketing firm Hill Holliday of Generation Z – people born after 1995 – half of those surveyed stated they had quit or were considering quitting at least one social media platform. When it comes to Gen Z’s relationship to social media, “significant cracks are beginning to show”, says the firm’s Lesley Bielby.
This instant messaging network is similar to WhatsApp and is available across platforms in more than eight languages.

Founded on December 14, 2002, and launched 0n May 5, 2003, LinkedIn is hands-down the most popular social media site for professional networking. The website is available in 24 languages and has over 400 million registered users. LinkedIn is great for people looking to connect with people in similar industries, networking with local professionals and displaying business related information and statistics.
Pinterest is a social curation website for sharing and categorizing images found online. Pinterest requires brief descriptions but the main focus of the site is visual. Clicking on an image will take you to the original source, so, for example, if you click on a picture of a pair of shoes, you might be taken to a site where you can purchase them. An image of blueberry pancakes might take you to the recipe; a picture of a whimsical birdhouse might take you to the instructions.
Efforts to combat selective exposure in social media may also cause an increase in political polarization.  A study examining Twitter activity conducted by Bail et. al paid Democrat and Republican participants to follow Twitter handles whose content was different from their political beliefs (Republicans received liberal content and Democrats received conservative content) over a six week period.  At the end of the study, both Democrat and Republican participants were found to have increased political polarization in favor of their own parties, though only Republican participants had an increase that was statistically significant. 
This is a social news and entertainment networking website where registered users can submit content such as direct links and text posts. Users are also able to organize and determine their position on the site’s pages by voting submissions up or down. Submissions with the most positive votes appear in the top category or main page. Reddit was founded by University of Virginia roommates Alexis Ohanian and Steve Huffman on June 23, 2005. A decade later, the site boasts more than 36 million registered accounts and 231 million monthly visitors.
Another way influencers can make money from digital products is to co-create content with brands, either by selling advertising and editorial space to them, or by being commissioned specifically to create content. An example of this strategy in action is Gritty Pretty, a beauty website and digital magazine founded and edited by Australian beauty editor Eleanor Pendleton. Eleanor created Gritty Pretty to share and monetize her beauty tips, knowledge, recommendations and experience with her audience, and works with brands to create sponsored content, editorial and ads to ultimately fund the magazine and support her team.
