7．In the days before bootleg（非法销售）DVDs，anyone who lived in China during the early 1990s will remember how terribly exciting it was when a foreign film was screened ln the cinema．Only 20foreign films a year were allowed to be shown in Chinese cinemas until February 2012．
The US film industry has shown a lot of interest in developing its business in China．The reasons for this are clear． China has a population of over 1.3billion and，with the standard of living rising all the time，the US film industry wants a slice （一片）of the profits．There are thousands of new cinemas being added throughout China．Technology is also improving all the time，meaning that more and more cinemas are able to show films in 3D or IMAX format（形式）．
There is now a greater possibility of the US film industry earning more from the Chinese market．Now an agreement has been signed that will allow the number of foreign films a year to be increased to 34．This agreement with China will offer thousands of Americans jobs in and around the film industry．In addition，studios will be able to get 25%of the box office proceeds（收益），This was previously limited to about 13.5%． The real winners of the agreement will be The China Film Group and the Chinese cinema owners who make the largest profits．
The new deal is a huge step in the right direction．Even better．it will hopefully cut down on the Chinese bootleg DVD industry，which has long taken advantage of the fact that most Western films won't be shown in Chinese cinemas．
