The Chicago Bulls wordmark logo has been a part of the team’s identity since its inception in 1966, particularly in relation to the Chicago Bulls Primary logo. The original design was created by renowned graphic designer, Saul Bass, and featured a bold red bull with an angry expression on its face. This logo was used until 1985 when it underwent some slight modifications to modernize the look and feel of the brand. The most notable changes were made to the horns which were lengthened and curved slightly outward for better visibility from afar as well as a more aggressive appearance overall.

In 1993, another update brought about even bigger changes to this iconic symbol; gone was Saul Bass' original design in favor of one featuring two bulls facing each other head-to-head surrounded by flames that encircled them both along with “Chicago Bulls” written across their backsides in white lettering against a black background. This new look became synonymous with Michael Jordan's legendary run during his tenure at Chicago Bulls where he won six NBA championships under this very same emblematic representation of strength & power that still stands today after 25 years!

Since then there have been no major alterations done (except for minor tweaks) but what remains constant is how deeply embedded into sports culture & history this classic image has become over time - making it instantly recognizable worldwide whether you're talking about basketball or not! It truly speaks volumes about what kind of legacy these great players left behind through their hard work and dedication while wearing those famous red uniforms adorned with such timeless wordmark logos representing all things "Bulls."
