Definition
A microblogging and social networking platform known for its strong fandom communities, creative subcultures, and long-form text posts. Tumblr was a dominant platform for fan fiction, fan art, and internet culture from 2007 through the mid-2010s. Its 2018 adult content ban caused a significant user exodus, but it retains active communities in niche creative spaces. Tumblr is historically significant as an early platform for creator community building.
