The document discusses how new media technologies were used at various stages of creating a teaser trailer. It describes using software like Garageband to create music, Imovie to edit video clips, and Photoshop to design posters. Hardware like digital cameras, microphones, and scanners were also used. Many of these technologies like Imovie and Garageband did not exist 10 years ago, so the process would have been more difficult and time consuming without advanced editing software. Social media sites like Blogger and Soundcloud were also utilized, and those too were not options 10 years ago for sharing work.
