Igo Shinpo (囲棋新報 Igo News 1879-1924) was the world's first go magazine, published monthly by Hoensha, with Honinbo Shuho (and later heads of Hoensha) as the editor in chief. Essentially a collection of games played in Hoensha monthly meetings with some simple comments. 520 issues were published. Each issue sold more than 1,000 copies.
Hoensha also published Igo Shogaku Shinpo (囲碁初学新報) for novice readers from 1900 to 1913.
