Top Social Networking Sites

Facebook jumped by 100 million monthly active users from 2.13 billion in December 2017 to 2.23 billion as of June 30, 2018. The rate of growth seems to continue at 15 million active users per month. So, by the end of the year we should see 2.35 billion Facebook monthly active users. Here’s the post where Zuckerberg announced the news about reaching the 2 billion milestone:

Again, on this graph you can see the three large circles dominating the rest. Only Twitter and Reddit battling it out for the fourth space seem to come close to the top 3. However, in Russia VK has a huge penetration, dominating the Russian speaking world as Facebook does globally.

Youtube has added 300 million people to its logged-in audience in less than a year. I believe this trend to continue and Youtube might reach 2 billion people within next 10 months.

Top Social Networking Apps

With the growing popularity of mobile social networking, we have also created a list of 10 leading social apps globally. These apps are in fierce competition with the main social sites already!

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.

  • WhatsApp added another 200 million monthly active users reaching 1.5 billion. Facebook Messenger promptly added another 100 million users and now they are behind WhatsApp with 1.3 billion monthly active users. Both of these mobile platforms are owned by Facebook.
  • WeChat took the 3rd position as it passed QQ and Instagram with more than 189 million monthly active users as QQ continues to slide.

Social Networking App

Monthly Active Users

WhatsApp (owned by Facebook) 1,500,000,000
Messenger (owned by Facebook) 1,300,000,000
WeChat 989,000,000
Instagram (owned by Facebook) 800,000,000
QQ Chat 783,000,000
QZone 652,000,000
Viber 249,000,000
LINE 218,000,000
Snapchat 200,000,000
YY 122,000,000

Social networking apps are going to grow even bigger as people adopt them into their everyday lives. Here we have listed the mobile-first social media platforms. But the Facebook mobile app would dominate this list with 1.37 billion monthly active users. As smartphones’ adoption continues, the share of the desktop use of social media platforms will fall .

For a list of social media apps that are smaller check List of virtual communities with more than 100 million active users from Wikipedia.
