Social media refers to web-based platforms that allow users to create, share, and interact with content in real time. Emerging in the early 2000s with platforms like Friendster and MySpace, it exploded globally with Facebook (2004), Twitter (2006), and Instagram (2010), ultimately reaching over 5 billion active users by 2024. It has reshaped journalism, politics, commerce, and personal identity faster than any communications technology in history.
How Did Social Media Begin and Evolve?
The earliest social networks date to SixDegrees.com (1997), which let users create profiles and list friends. Friendster launched in 2002 and attracted 3 million users within months, proving mass appetite for online social connection. MySpace (2003) became the world's most visited website by 2006, peaking at 100 million accounts. Mark Zuckerberg launched Facebook from his Harvard dorm in February 2004; by 2008 it had surpassed MySpace in global traffic. Twitter debuted in 2006, pioneering the 140-character public post. YouTube (2005), acquired by Google for $1.65 billion in 2006, transformed video sharing. Instagram launched in October 2010 and reached 1 million users in 75 days. Snapchat (2011), TikTok (2016), and BeReal (2020) each introduced new formats—ephemeral posts, short-form video, and unfiltered authenticity—keeping the ecosystem in constant evolution.

What Impact Has Social Media Had on Politics and Society?
Social media's political power became undeniable during the 2008 U.S. presidential election, when Barack Obama's campaign raised $500 million online and mobilised millions via Facebook and Twitter. The Arab Spring of 2010–2012 showed how platforms could coordinate mass protests, toppling governments in Tunisia and Egypt. By 2016, algorithmic amplification of misinformation was implicated in Brexit and the U.S. election. The January 6, 2021 Capitol riot prompted Twitter and Facebook to permanently ban then-President Donald Trump, igniting fierce debate over platform power and free speech. Studies by the Pew Research Center (2022) found that 48% of U.S. adults get news from social media regularly, while the Reuters Institute found trust in social-media news at just 26% globally—lower than any traditional outlet.

What Are the Key Harms and Benefits of Social Media?
The benefits are tangible: instant global communication, democratised publishing, grassroots fundraising, and community-building for marginalised groups. The harms are equally documented. A 2021 Wall Street Journal investigation revealed Facebook's internal research showing Instagram worsened body image in 32% of teenage girls. The World Health Organization linked excessive social media use to anxiety and depression in adolescents. Cyberbullying affects approximately 37% of young people aged 12–17 in the U.S., according to the Cyberbullying Research Center. On the economic side, the global social media advertising market reached $227 billion in 2023, making platforms among the most profitable businesses ever built—funded almost entirely by harvesting user attention and data.
