Passage: Public radio was introduced in New Zealand in 1922. A state-owned television service began in 1960. Deregulation in the 1980s saw a sudden increase in the numbers of radio and television stations. New Zealand television primarily broadcasts American and British programming, along with a large number of Australian and local shows. The number of New Zealand films significantly increased during the 1970s. In 1978 the New Zealand Film Commission started assisting local film-makers and many films attained a world audience, some receiving international acknowledgement. The highest-grossing New Zealand films are Hunt for the Wilderpeople, Boy, The World's Fastest Indian, Once Were Warriors and Whale Rider. The country's diverse scenery and compact size, plus government incentives, have encouraged some producers to shoot big-budget productions in New Zealand, including Avatar, The Lord of the Rings, The Hobbit, The Chronicles of Narnia, King Kong and The Last Samurai. The New Zealand media industry is dominated by a small number of companies, most of which are foreign-owned, although the state retains ownership of some television and radio stations. Since 1994, Freedom House has consistently ranked New Zealand's press freedom in the top twenty, with the 19th freest media in 2015.
