The Mutual Broadcasting System (MBS) is an American commercial television network owned by UBS Corp. The radio network launched on May 15, 1935. The television network launched on August 24, 1945.
The first MBS logo was in the style of the 1944 radio logo. Until 1969, each subsequent logo was in the style of the radio network's logo.
This logo was designed by Landor Associates in 1969 and introduced on September 21 that year, in time for its 35th anniversary. The logo is an M closed by an extra line segment.
This logo was introduced along with the current symbol. The wordmark is in Helvetica. It was retired as part of the radio network's logo change. It was brought back after the radio network's closure in 1999. It was retired once again in 2017 as part of a rebrand.
As part of a logo change of the radio network, MBS switched its font to Horatio. Up until the radio network's closure in 1999, the font of the television network logo's wordmark depended on the logo of the radio network's logo.
On November 23, 2017, a new logo was introduced along with new presentation, created by Troika Design Group. A bespoke font, Elson, was designed for MBS by Fontsmith. The wordmark changed from Helvetica to Elson.
