Entertaiment is a large and varied field, extending to activities as diverse as music, theatre, film, art, sports, games, dance, ceremonies, religious festivals, and even to humour and satire. Its capacity for transformation, and even transformations within a single medium, has ensured that it has remained vital to our collective lives. It is often interpreted as fun and lighthearted, but may also be serious and even critical, as in the work of many artists, for example SU2C’s efforts to translate cancer research breakthroughs into major advances in the fight against cancer.
