The picture here is a bit different if we look at the brand names. WhatsApp and Messenger are in a close race for the top spot. But both of these most popular social media apps are owned by Facebook so the competition may not be as fierce as between completely separate companies. Then there’s a lot of Asian apps and then on the sixth spot is Instagram, again owned by Facebook.
Social media might can also function as a supportive system for adolescents' health, because by using social media, adolescents are able to mobilize around health issues that they themselves deem relevant. For example, in a clinical study among adolescent patients undergoing treatment for obesity, the participants' expressed that through social media, they could find personalized weight-loss content as well as social support among other adolescents with obesity The same authors also found that as with other types of online information, the adolescents need to possess necessary skills to evaluate and identify reliable health information, competencies commonly known as health literacy.
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. 
Most social media accounts post random thoughts and information that doesn’t target any specific demographic. If you intend to earn money through social media, however, it is important to focus on a single subject which you are good at or to pick a specific area to concentrate on. You should then tailor all your posts to fit into the niche you have settled on.
But quitting social media can create new anxieties. “Our research shows that the biggest fear of quitting or pausing social media is missing out,” Bielby says. Some are more sanguine than others. “Do I miss out on stuff?” Morgan asks. “Yeah, of course. People find it hard to keep in contact with me. They say: ‘It would be easier if you had this or that.’ But I don’t think it’s that hard to type in my number and send a text. You’re just not willing to do it.”

Digital products give influencers the opportunity to create something tangible that they can distribute and sell to their network to earn an income from their knowledge, influence and expertise. Fitness queen Kayla Itsines is a great example of an influencer empire built on digital products and influence, with her downloadable workout program Bikini Body Guide and her newly launched app Sweat With Kayla.
In the early days of social marketing, there was little competition for the dollar—not so today. For example, you can spend thousands of dollars on a Facebook ad campaign and, sometimes, get no return on your investment. By its very nature, social media is a short attention span media—it is much harder to get someone's attention with a Tweet then it was to get someone's attention with a newspaper ad. That's because ad headlines and copy are harder to write on Twitter or Instagram.
Recent research has demonstrated that social media, and media in general, have the power to increase the scope of stereotypes not only in children but people all ages. Three researchers at Blanquerna University, Spain, examined how adolescents interact with social media and specifically Facebook. They suggest that interactions on the website encourage representing oneself in the traditional gender constructs, which helps maintain gender stereotypes. The authors noted that girls generally show more emotion in their posts and more frequently change their profile pictures, which according to some psychologists can lead to self-objectification. On the other hand, the researchers found that boys prefer to portray themselves as strong, independent, and powerful. For example, men often post pictures of objects and not themselves, and rarely change their profile pictures; using the pages more for entertainment and pragmatic reasons. In contrast girls generally post more images that include themselves, friends and things they have emotional ties to, which the researchers attributed that to the higher emotional intelligence of girls at a younger age. The authors sampled over 632 girls and boys from the ages of 12–16 from Spain in an effort to confirm their beliefs. The researchers concluded that masculinity is more commonly associated with a positive psychological well-being, while femininity displays less psychological well-being. Furthermore, the researchers discovered that people tend not to completely conform to either stereotype, and encompass desirable parts of both. Users of Facebook generally use their profile to reflect that they are a "normal" person. Social media was found to uphold gender stereotypes both feminine and masculine. The researchers also noted that the traditional stereotypes are often upheld by boys more so than girls. The authors described how neither stereotype was entirely positive, but most people viewed masculine values as more positive.
Information can be shared through social media at an amazingly fast pace, and users are increasingly turning to social channels to share information in real-time. This information often takes the form of opinions, so if you're listening for the right cues from your audience, social media can become an invaluable source of insights and feedback. Incorporating social listening into product development work can act as an early warning system, save on customer service costs, provide valuable development feedback, and even help identify ideal beta testers without much expense.
