One of the oldest sports franchises in US history, the Chicago Cubs have been continually playing in the same city since 1870. Their logo has changed many times over the year, starting as a Old English C. The C shape changed several times over the years, sometimes represented with a bear or 'ubs' inside the C to create the team name. This logo came into use in 1979 when a thicker blue circle was introduced to replace the thin blue circle that was used from 1957-1978.
