The first individual trampolining competitions were held in colleges and schools in the USA and then in Europe. In the early years of competition there was no defined format with performers often completing lengthy routines and even remounting if falling off partway through. Gradually competitions became more codified such that by the 1950s the 10-bounce routine was the norm thereby paving the way for the first World Championships which were organised by Ted Blake of Nissen, and held in London in 1964. The first World Champions were both American, Dan Millman and Judy Wills Cline (both pictured to the right together with members of the Household Cavalry at the closing ceremony). Kurt Baechler of Switzerland and Ted Blake of England were the European pioneers and the first ever televised National Championships were held in England in 1958.
