in a "golden age" of popularity for professional boxing in the 1920s. They were also responsible for the first live radio broadcast of a title fight (Dempsey v. Georges Carpentier, in 1921). In the United Kingdom, Jack Solomons' success as a fight promoter helped re-establish professional boxing after the Second World War and made the UK a popular place for title fights in the 1950s and 1960s. Modern history 1900 to 1920 In the early twentieth century, most professional bouts took place in the United States and Britain, and champions were recognised by popular consensus as expressed in the newspapers of the day. Among the great champions of the era were the peerless heavyweight Jim Jeffries and Bob Fitzsimmons, who weighed less than 12 stone (164 pounds), but won world titles at middleweight (1892), light heavyweight (1903), and heavyweight (1897). Other famous champions included light heavyweight Philadelphia Jack O'Brien and middleweight Tommy Ryan.
