Medium Online Publishing Platform
Medium is an American online publishing platform developed by Evan Williams and launched in August 2012. It is owned by A Medium Corporation.[2] The platform is an example of social journalism, having a hybrid collection of amateur and professional people and publications, or exclusive blogs or publishers on Medium,[3] and is regularly regarded as a blog host.

Williams, previously co-founder of Blogger and Twitter,[4] initially developed Medium as a means to publish writings and documents longer than Twitter's 140-character (now 280-character) maximum.

In March 2021, Medium announced a change in its publishing strategy and business model. The change is to its mix of paid journalists working on its own publications – this will be proportionally reduced – versus its support of independent writers, which will increase.
