Yahoo paid $1.1 billion for Tumblr in 2013. Six years later, Automattic — the WordPress people — bought it for roughly $3 million. A $1.097 billion value destruction event, executed through a series of completely predictable decisions. David Karp got out early with his money. The users stayed. The advertisers never came.

tumblr.comTHE ORIGIN STORY
David Karp launched Tumblr at 20 years old, having dropped out of school at 14 to pursue programming. He wanted a blogging platform that was easier than WordPress and more expressive than Twitter — somewhere between the two, designed for sharing media in a stream.
The platform found its community: young, creative, fan-fiction-writing, art-sharing, queer-friendly internet denizens who used it as their creative outlet. At its 2013 peak, Tumblr had 300 million unique monthly visitors and Yahoo bought it for $1.1 billion, promising to "not screw it up." Yahoo screwed it up.
WHAT THEY ACTUALLY DO
Tumblr was a microblogging and social platform where users could post text, photos, quotes, links, music, and videos. Its revenue model was advertising — display ads served to its enormous traffic base.
At its peak it hosted over 500 million blogs and hundreds of millions of daily posts. The advertising model never generated revenues proportional to that traffic.
Yahoo could not monetize it. Verizon could not monetize it.
Automattic bought it for the traffic and the brand.
THE PRODUCTS
Tumblr blogging platform (text, photo, video, quote, audio posts), Tumblr dashboard feed, Tumblr messaging, various customization themes
HOW THEY GREW
Every owner tried variations of the same playbook: advertising, brand partnerships, native content. None of it worked at sufficient scale.
Tumblr's real value was the culture of its community, which is not something you can sell to advertisers without destroying it.
THE HARD PART
Tumblr's core users were not the users advertisers wanted to reach. Or rather, Tumblr's most engaged users were teenagers and young adults who were ad-resistant and who built a culture that was hostile to corporate intrusion.
Yahoo tried to run traditional display ads and alienated the community. Then Verizon acquired Yahoo in 2017 and tried the same thing.
Apple removed Tumblr from its App Store in 2018 over child safety concerns. Tumblr responded with a blanket ban on all adult content — which deleted roughly one-third of its active content and alienated a massive chunk of its user base in a single announcement.
