Question

the economy of making movies is changing give reason​

Answer 1

Film has a uniquely powerful ubiquity within human culture. In 2009, across major territories, there were over 6.8 billion cinema admissions (compared against a world population of roughly the same number) creating global box office revenues of over US$30 billion. The convergent nature of film creates consumption across a number of channels. In the same year combined DVD and Blu-Ray sales in the United States, Canada and European Union alone were US$32.5 billion (amounting to over 1.1 billion units sold). When you start to then consider revenues and audience figures from those who consume digitally, via television, repeat view content they already own and view through the highly illegal but vast black-market in films, the figures become truly staggering.
