Launched #otd in 2007 by #DavidKarp, the microblogging platform #Tumblr quickly gained popularity among creatives for its customizable templates and user-friendly interface in the late 2000s. In 2013, Yahoo acquired Tumblr for $1.1 billion, but struggled to monetize its large user base. In 2017, Verizon purchased Yahoo and later sold Tumblr to Automattic in 2019 for $3 million. Despite a decline in user numbers, Tumblr remains a go-to platform for sharing and discovering creative content. 🎂
