of new dances. Beginning in the mid-1930s, national organizations began to introduce skating proficiency tests in set-pattern dances, improve the judging of dance tests, and oversee competitions. The first national competitions occurred in England in 1934, Canada in 1935, the U.S. in 1936, and Austria in 1937. These competitions included one or more compulsory dances, the original dance, and the free dance. By the late 1930s, ice dancers swelled memberships in skating clubs throughout the world, and in Hines' words "became the backbone of skating clubs". The ISU began to develop rules, standards, and international tests for ice dance in the 1950s. The first international ice dance competition occurred as a special event during the 1950 World Figure Skating Championships in London; Lois Waring and Michael McGean of the U.S. won the event, much to the embarrassment of the British, who considered themselves the best ice dancers in the world. A second event was planned the following year, at the 1951 World Championships in Milan; Jean Westwood and Lawrence Demmy of Great Britain came in first place. Ice dance, with the CD and FD segments, was formally added to the World Championships in 1952. Westwood and Demmy won that year, and went on to dominate ice dance, winning the next four World Championships as well. British teams won every world ice dance title through 1960. Eva Romanova and Pavel Roman of Czechoslovakia were the first non-British ice dancers to win a world title, in 1962. 1970s to 1990s Ice dance became an Olympic sport in 1976; Lyudmila Pakhomova and Alexandr Gorshkov from the Soviet Union were the first gold medalists. The Soviets dominated ice dance during most of the 1970s, as they did in pair skating. They won every Worlds and Olympic title between 1970 and 1978, and won medals at every competition between 1976 and 1982. In 1984, British dancers Jayne Torvill and Christopher Dean, who Hines calls "the greatest ice dancers in the history of the sport", briefly interrupted Soviet domination of ice dance by winning a gold medal at the Olympic Games in Sarajevo. Their free dance to Ravel's Boléro has been called "probably the most well known single program in the history of ice dance". Hines asserts that Torvill and Dean, with their innovative choreography, dramatically altered "established concepts of ice dancing". During the 1970s, there was a movement in ice dance away from its ballroom
