The power of television is undeniable. When gorillas were first introduced to Longleat Zoo's Gorilla Island and had to be quarantined and initially segregated from each other, the wardens came up with the rather smart idea of building TVs in their enclosures to keep them occupied. The gorillas loved it so much that when they came to take it away, they protested and sulked so violently that they were forced to put them back in. Now their living quarters come with Sky Digital satellite dishes fixed to the roof. According to the zoo officials, they are particularly fond of Spongebob Squarepants and other children's programmes.
