Tumblr vs. Other Social Networking Platforms

Social Network Usage in the USA

The United States is the most popular user-base for Tumblr and has always been the most popular one as well. However, although the USA generates half of the traffic for Tumblr, the country itself doesn’t rate Tumblr as its most popular platform and falls short by a considerable margin.

Among Teenagers

  • In 2015, 4% of the teenagers used Tumblr in 2015 as opposed to 29% of teens using Instagram, 21% using Twitter, 12% using Facebook, and 11% using Snapchat.
  • In 2016, only 2% of the teens in the USA used Tumblr, whereas Snapchat popularity rose to 24%, Instagram reduced to 23%, Twitter was at 16%, and Facebook was at 15%.
  • Tumblr kept on seeing a reduction in its teenage popularity, holding 1% of the market as Snapchat acquired 39% of the US teen social networking market, Twitter and Facebook had 11% share each and Instagram stayed at 21%.
  • By 2018, Snapchat was the most popular social network, with 45% of the US market, and Instagram was 26% of the market. Twitter had 9% of the social network app, and Facebook reduced to 8%. Tumblr stayed at 1%.
  • However, in 2019 as Facebook’s share further reduced to 6% and Instagram popularity increased to 35%, Tumblr now had less than 1% of the market, which for Tumblr was more than 45% of their traffic. Twitter’s share also reduced to 6% over that one year.

User Engagement in Mobile Social Networking Apps

A study in September 2019 conducted in the USA for 20,000 users aged 18 years or older to gauge the popularity of social networking apps in the country by analyzing their user engagement in minutes per month.

  • Facebook emerged as the leading network with the usage of 769 minutes per month. TikTok was second with 498 minutes of usage every month, Google messenger at 335.51 minutes monthly, followed by WhatsApp, Telegram, Discord, Instagram, and Snapchat.
  • However, Tumblr did not even make it to the top 10 social networking apps in the country with just 115.8 minutes of usage per month.

User Engagement in terms of Average Session Duration

The same study mentioned above also determined the average session duration for popular social networking apps.

  • TikTok topped the list with 10.85 minutes of average session duration in the USA.
  • Pinterest and Reddit came next at 5.06 and 4.96 minutes on average.
  • An average Facebook session lasted 4.82 minutes, whereas that of Instagram lasted only 2.95 minutes.
  • Tumblr, in that regard, had a higher session duration of 4.04 minutes.
  • However, the difference here was that although Tumblr had higher session duration, the number of sessions was quite low as compared to its popular competitors. Thus Tumblr still placed lower on overall popularity.

Number of Monthly Users

The study also determined the number of monthly users for September among popular apps.

  • Facebook had the highest number of monthly users of 169.76 million users.
  • Instagram came second with 121.23 million users, followed by Facebook Messenger at 106.4 million users.
  • Twitter, although 4th on the list, had a user base of only 81.47 million users.
  • Tumblr made it to the 10th position on the list but only had 16.74 million monthly users.

Financial Growth of Tumblr


Since it started, there have been five rounds of funding for Tumblr.

  • The Series A round had 750,000 dollars in funding, while the Series B round accumulated 4.5 million in funding. The investors of Series A round included Sequoia Capital, Insight Venture Partners, Union Square Ventures, and Spark Capital.
  • Series C also roughly gathered 5 million dollars. Series D round was slightly more successful, raking around 30 million dollars.
  • However, it was the Series E round, which brought in the highest funding of more than 85 million dollars across 10 investors in September 2011.


  • After introducing advertisements, Tumblr made 13 million revenue in 2012.
  • The company hoped to do 100 million+ revenue in 2013; however, it has never quite risen to task in handling its revenue growth as Yahoo failed to achieve the 100 million mark in 2015 as well, after acquiring Tumblr.
  • As of the latest 2019 report, the company has done 65 million in revenue, which is a shabby growth from the number of ownerships and funding the company has had.

Revenue Sources

Based on the business model, Tumblr has four revenue sources.

  • It allows advertisements in the form of sponsored posts by brands that can target specific users based on their demographics. These sponsored posts also appear in the side panel of the website, just like traditional ads.
  • Another revenue stream is through display ads, which are known as Video Posts on Tumblr. The only difference is that these are in the video format, as opposed to the traditional post format.
  • Tumblr has a unique revenue model through Sponsored Day, where it allows a business or a brand to pin their logo and tagline to the top of the dashboard and the Explore pages for 24 hours.
  • The fourth revenue stream is ‘Premium Themes,’ wherein Tumblr offers its users access to a premium theme for their blogs, which can cost anywhere between 9 to 19 dollars.


Since the NSWF ban,  Tumblr lost a lot of traction on its website, as well as the app. Users have shifted to platforms where their freedom to express stays unharmed. Although the microblogging platform started on a very high note, the success has been a rollercoaster, and after several big names in the industry have failed to help Tumblr in reaching a stable position in the social networking space. seems to be the final straw in the hat.

The WordPress acquisition of Tumblr at a dirt-cheap rate has not reduced the challenges facing the globally recognized blogging platform. While Tumblr is doing fairly well in its position as a complement to, only the future will reveal the scope of growth for Tumblr and its sustenance in the microblogging world.
