In the 1960s, Roller Games experienced rapid growth, and established teams in Baltimore, Cleveland, Philadelphia, Florida, Hawaii, Canada, Mexico, Australia and Japan. Roller Games eventually encompassed several separate leagues: National Roller Derby (NRD), which was renamed to National Roller League (NRL); Canadian National Roller League (CNRL); and Japanese National Roller League (JNRL). Aside from the L.A. Thunderbirds, NRD/NRL teams over the years included the Chicago Hawks, Detroit Devils, New York Bombers, Texas Outlaws, Philadelphia Warriors, and Brooklyn Red Devils. Many matches were broadcast live on Los Angeles television affiliate KTLA, with Dick Lane calling the play-by-play. He was famous for saying "Whoaaaa, Nelly" (predating Keith Jackson) when fights broke out between the players. Lane's play-by-play was often assisted in the press box and on the infield by Bill "Hoppy" Haupt. The Olympic Auditorium was the league's primary venue. Eventually, the flagship station for Thunderbirds games was changed to KCOP, with taped repeats appearing in prime time on KBSC.
