Medium is an online publishing platform developed by Twitter co-founder Evan Williams, and launched in August 2012. Medium is a host to both amateur and professional writers' publications and blogs.
Anyone can publish on Medium, and everyone’s posts look the same. There are no themes or customization, and the only thing that separates one post from another is the quality of the content. It is primarily a place to read, write and interact with the stories that matter most to users.
Medium’s original logo was a bold letter ‘M’ that played with a classic black and white combination. Two versions of this logo were used -- a black letter ‘M’ on a white background, and a white letter ‘M’ on a black background.
Medium rebranded in 2015 with a more flexible interchangeable identity, based on the idea of the “overlapping strands of a conversation.”
The new identity included a logo that featured an abstracted letter ‘M’ -- designed with a 3D effect -- in green shades that ranged from forest green to neon green (above left). While the new logo gave Medium a fresh and creative look, the company has redesigned its logo again (above right). Earlier in 2017, Medium revealed a new logo, which resembles their original identity.
