The club's first logo was introduced in the early 1950s as a black bear on top of a football. They kept this until 1962, when the Bears trademark 'C' logo was first introduced.
The change in their logo from the black bear was due to the addition of logos on helmets, which pro football teams started adding in the late 1950s and early 1960s. Unlike some NFL franchises that have had many different looks over time, the Bears have kept the wishbone 'C' for over 40 years.
In 1974, the team decided to keep the same 'C' logo but change the color from white to orange with white trim. This is the current logo; however, the club has since introduced alternate logos, including a black bear inside of the orange wishbone 'C', introduced in 1995, and an orange bear head, introduced in 1999.
