Amazon Unbox. The Amazon Unbox was introduced in 2006. Users download films or TV shows to the Amazon Unbox Player or on Windows Media Player. In addition, Amazon established a partnership with TiVo in 2007 that allows consumers to purchase movies or TV shows through Amazon.s Unbox and send it to the TiVo machine to view. Amazon's service is similar to its competitors in that once a movie or show is downloaded, it must bw viewed within 30 days and once it is started, it must be viewed within 24 hours. Amazon also has agreements with most of the major movie studio such as Paramount Pictures, Universal Studios, Warner Bros., CBS, and Fox. NBC contracted with Amazon to offer its TV shows for download after NBC cancelled its agreement with Apple for the iTunes service.
