Although the origin of the word "dance" is uncertain, dance itself has been impacting cultures for more than 9,000 years. Today's dancing incorporates many styles and moods, but the most popular contemporary dances are ballet, jazz, modern, and hip hop.
In recent years, TV reality shows like "So You Think You Can Dance" and "Dancing with the Stars" have brought the art of dance into the limelight and generated a renewed interest in professional and amateur competitive dancing.
