Hint:
Strictly Come Dancing
Ballroom dancing used to be seen as something rather unfashionable that old people might do. For the past five years though, the popularity of ballroom dancing has soared thanks to a reality TV show. Strictly Come Dancing is one of the big TV shows. Millions of people tune in every Saturday night to watch the show which airs from September right up to Christmas. In the show a number of professional ballroom dancers each dance with a celebrity. Every week they have to learn a different ballroom dance and perform it live on TV on Saturday night. The show demonstrates how glamorous ballroom dancing is. The celebrities get to wear colorful dresses and suits to dance in, and it looks like a lot of fun. The TV programme also shows what good exercise it can be to ballroom dance and what hard work is involved in learning the dances and performing them properly. Dance schools around the country have seen a boost in the number of people wanting to learn how to dance. And it's not only old people who are interested. Lots of children and young people in their 20s are keen to learn.
