Linkedin is a professional social networking platform where users can create a profile, connect with other professionals, showcase their skills and experiences, and find job opportunities.
Linkedin's current logo features a bold black logotype with the "in" portrayed in white within a blue rounded box. Previously, the font used was Myriad, but it was updated to the geometric sans Avenir Black in December 2012 or earlier. You can purchase and download Avenir Black here.
