Tumblr still has a sizable and active user base with more than 450 million blogs and 172 billion posts, but it has been steadily declining as its corporate owners have struggled to figure out exactly what to do with the platform. Yahoo acquired Tumblr for $1.1 billion in 2013 as part of then-CEO Marissa Mayer's buying spree but was unable to leverage the young users into meaningful revenue. When Verizon purchased Yahoo for $4.5 billion in 2017, it took ownership of Tumblr, placing it under its media umbrella Oath (now Verizon Media Group).
Like Yahoo before it, Verizon couldn't figure out how to handle Tumblr. Last year, the telecom changed Tumblr's policy to block adult content, prohibiting any images or videos that depict "human genitals or female-presenting nipples." The decision led to a significant drop in traffic to the blogging platform, which was predictable because everyone knows the internet is for porn.
