On April 10, 2018, in a hearing held in response to revelations of data harvesting by Cambridge Analytica, Mark Zuckerberg, the Facebook chief executive, faced questions from senators on a variety of issues, from privacy to the company’s business model and the company's mishandling of data. This was Mr. Zuckerberg’s first appearance before Congress, prompted by the revelation that Cambridge Analytica, a political consulting firm linked to the Trump campaign, harvested the data of an estimated 87 million Facebook users to psychologically profile voters during the 2016 election. Zuckerburg was pressed to account for how third-party partners could take data without users’ knowledge. Lawmakers grilled the 33-year-old executive on the proliferation of so-called fake news on Facebook, Russian interference during the 2016 presidential election and censorship of conservative media.
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."
Having social media in the classroom was a controversial topic in the 2010s. Many parents and educators have been fearful of the repercussions of having social media in the classroom. There are concerns that social media tools can be misused for cyberbullying or sharing inappropriate content. As result, cell phones have been banned from some classrooms, and some schools have blocked many popular social media websites. Many schools have realized that they need to loosen restrictions, teach digital citizenship skills, and even incorporate these tools into classrooms. Some schools permit students to use smartphones or tablet computers in class, as long as the students are using these devices for academic purposes, such as doing research. Using Facebook in class allows for integration of multimodal content such as student-created photographs and video and URLs to other texts, in a platform that many students are already familiar with. Twitter can be used to enhance communication building and critical thinking and it provides students with an informal "back channel"), and extend discussion outside of class time. YouTube is a frequently used social media tool in the classroom.[not in citation given] Students can watch videos, answer questions, and discuss content. Additionally, students can create videos to share with others.
Social media is being used in a range of court cases including employment law, child custody/child support and insurance disability claims. After an Apple employee criticized his employer on Facebook, he was fired. When the former employee sued Apple for unfair dismissal, the court, after seeing the man's Facebook posts, found in favour of Apple, as the man's social media comments breached Apple's policies. After a heterosexual couple broke up, the man posted "violent rap lyrics from a song that talked about fantasies of killing the rapper’s ex-wife" and made threats against him. The court found him guilty and he was sentenced to jail. In a disability claims case, a woman who fell at work claimed that she was permanently injured; the employer used her social media posts of her travels and activities to counter her claims.
Relationships flourish when you cultivate them, and no other area offers you the opportunity to do this as well as social media. Social channels have broken down the walls between individuals at an unprecedented rate. In 2011, Facebook released data showing that its users were, on average, 3.74 degrees of separation away from one another, making them nearly as connected to each other as Kevin Bacon is to the rest of Hollywood. In the years since that study, the network has only continued to grow. That's pretty amazing, and social media can take credit for making it happen.
The variety of evolving stand-alone and built-in social media services makes it challenging to define them. However, marketing and social media experts broadly agree that social media includes the following 13 types of social media: blogs, business networks, collaborative projects, enterprise social networks, forums, microblogs, photo sharing, products/services review, social bookmarking, social gaming, social networks, video sharing, and virtual worlds.
