After the war, the boogie became the dominant form for popular music. It was, however, never far from criticism as a foreign, vulgar dance. The famous ballroom dancing guru, Alex Moore, said that he had "never seen anything uglier". English instructors developed the elegant and lively ballroom Jive, danced to slightly slower music. In 1968 it was adopted as the fifth Latin dance in International competitions. The modern form of ballroom jive in the 1990s-present, is a very happy and boppy dance, the lifting of knees and the bending or rocking of the hips often occurs.
