Meta Controls the World’s Largest Social Platforms
Facebook, created in 2004, is owned by Meta (formerly Facebook Inc.), one of the world’s largest companies by market capitalization.
Yet Meta’s dominance extends well beyond Facebook, as it also owns runners-up Instagram and WhatsApp (both 3 billion). Meta acquired Instagram for just $1 billion in 2012, and acquired WhatsApp two years later for nearly $20 billion.
The table below lists the 15 most popular social media platforms worldwide alongside their owners and monthly active users.

While Facebook is popular with people of all ages, Instagram has become especially popular among young adults and millennials. Meanwhile, WhatsApp has become the world’s most widely used messaging app and is essential for communication in countries like Brazil and India.
Beyond the Big 3, Meta also owns Messenger (1 billion), another popular messaging app integrated with Facebook, as well as Threads (400 million), an Instagram offshoot designed to compete with X and its roughly 650 million users.
China’s Emergence in Social Media
While most of the world’s top social media platforms have historically been American, Chinese companies have rapidly expanded their influence in recent years.
Within China itself, Tencent’s WeChat (1.4 billion) has become the country’s primary digital platform, extending beyond messaging to include payments, shopping, and gaming.
Then there’s ByteDance, which has reshaped the global social media landscape. The company created Douyin (755 million) for the Chinese market and its international counterpart TikTok (2 billion), which has become one of the world’s fastest-growing social platforms.
TikTok’s widespread popularity, especially among younger users, has also triggered regulatory scrutiny and restrictions in countries including India and the United States.
Following growing U.S. restrictions on TikTok, ByteDance agreed to enter a joint venture with American companies in 2025.
Social Media Has Expanded Beyond Networking
When social media first originated in the 2000s, it was designed for young adults to stay connected. Facebook famously wanted to put the entire college experience online. However, since then social media has extended far beyond its initial purpose.
YouTube (2.5 billion) is the largest video-sharing site in the world, while Reddit (850 million) has become a massive online forum for people to congregate around shared interests.
Finally, there’s LinkedIn (310 million). The social networking platform was acquired by Microsoft for over $26 billion in 2016 and is today a central hub for working professionals in various sectors to connect, network, and find or advertise jobs.
